This advanced TMOS E–FET is designed to withstand high energy in the avalanche and commutation modes. The new energy efficient design also offers a drain–to–source diode with a fast recovery time. Designed for low voltage, high speed switching applications in power supplies, converters and PWM motor controls, these devices are particularly well suited for bridge circuits where diode speed and commutating safe operating areas are critical and offer additional safety margin against unexpected voltage transients. • Avalanche Energy Specified • Source–to–Drain Diode Recovery Time Comparable to a Discrete Fast Recovery Diode • Diode is Characterized for Use in Bridge Circuits • IDSS and VDS(on) Specified at Elevated Temperature • Short Heatsink Tab Manufactured — Not Sheared • Specially Designed Leadframe for Maximum Power Dissipation • Available in 24 mm 13–inch/800 Unit Tape & Reel, Add T4 Suffix to Part Number D G CASE 418B–02, Style 2 D2PAK S MAXIMUM RATINGS (TC = 25°C unless otherwise noted) Symbol Value Unit VDSS VDGR VGS 60 Vdc 60 Vdc ± 20 Vdc Drain Current — Continuous Drain Current — Continuous @ 100°C Drain Current — Single Pulse (tp ≤ 10 µs) ID ID IDM 15 10 40 Adc Total Power Dissipation Derate above 25°C Total Power Dissipation @ TA = 25°C, when mounted with the minimum recommended pad size PD 75 0.6 2.5 Watts W/°C Watts TJ, Tstg EAS – 55 to 150 °C 110 mJ RθJC RθJA RθJA 1.67 62.5 50 °C/W TL 260 °C Rating Drain–Source Voltage Drain–Gate Voltage (RGS = 1.0 MΩ) Gate–Source Voltage — Continuous Operating and Storage Temperature Range Single Pulse Drain–to–Source Avalanche Energy — Starting TJ = 25°C (VDD = 25 Vdc, VGS = 10 Vpk, IL = 15 Apk, L = 0.98 mH, RG = 25 Ω ) Thermal Resistance — Junction to Case Thermal Resistance — Junction to Ambient Thermal Resistance — Junction to Ambient, when mounted with the minimum recommended pad size Maximum Lead Temperature for Soldering Purposes, 1/8″ from case for 10 seconds Apk Designer’s Data for “Worst Case” Conditions — The Designer’s Data Sheet permits the design of most circuits entirely from the information presented.

Gate–to–Source and Drain–to–Source Voltage versus Total Charge 3 MTB15N06E POWER MOSFET SWITCHING Switching behavior is most easily modeled and predicted by recognizing that the power MOSFET is charge controlled. The lengths of various switching intervals (∆t) are determined by how fast the FET input capacitance can be charged by current from the generator. The capacitance (Ciss) is read from the capacitance curve at a voltage corresponding to the off–state condition when calculating td(on) and is read at a voltage corresponding to the on–state when calculating td(off). The published capacitance data is difficult to use for calculating rise and fall because drain–gate capacitance varies greatly with applied voltage. Accordingly, gate charge data is used. In most cases, a satisfactory estimate of average input current (IG(AV)) can be made from a rudimentary analysis of the drive circuit so that At high switching speeds, parasitic circuit elements complicate the analysis. The inductance of the MOSFET source lead, inside the package and in the circuit wiring which is common to both the drain and gate current paths, produces a voltage at the source which reduces the gate drive current. The voltage is determined by Ldi/dt, but since di/dt is a function of drain current, the mathematical solution is complex. The MOSFET output capacitance also complicates the mathematics. And finally, MOSFETs have finite internal gate resistance which effectively adds to the resistance of the driving source, but the internal resistance is difficult to measure and, consequently, is not specified. The resistive switching time variation versus gate resistance (Figure 8) shows how typical switching performance is affected by the parasitic circuit elements. If the parasitics were not present, the slope of the curves would maintain a value of unity regardless of the switching speed. The circuit used to obtain the data is constructed to minimize common inductance in the drain and gate circuit loops and is believed readily achievable with board mounted components. Most power electronic loads are inductive; the data in the figure is taken with a resistive load, which approximates an optimally snubbed inductive load. Power MOSFETs may be safely operated into an inductive load; however, snubbing reduces switching losses. t = Q/IG(AV) During the rise and fall time interval when switching a resistive load, VGS remains virtually constant at a level known as the plateau voltage, VSGP. Therefore, rise and fall times may be approximated by the following: tr = Q2 x RG/(VGG – VGSP) tf = Q2 x RG/VGSP where VGG = the gate drive voltage, which varies from zero to VGG RG = the gate drive resistance and Q2 and VGSP are read from the gate charge curve. During the turn–on and turn–off delay times, gate current is not constant. The simplest calculation uses appropriate values from the capacitance curves in a standard equation for voltage change in an RC network. The equations are: td(on) = RG Ciss In [VGG/(VGG – VGSP)] td(off) = RG Ciss In (VGG/VGSP) 4 Motorola TMOS Power MOSFET Transistor Device Data MTB15N06E 1000 1250 VGS = 0 1000 200 t, TIME (ns) C, CAPACITANCE (pF) VDD = 30 V ID = 15 A VGS = 10 V TJ = 25°C TJ = 25°C VDS = 0 750 Ciss 500 100 tf td(off) 20 td(on) 10 Coss 250 2 Crss 0 20 10 10 0 20 1 30 1 Figure 8.

Limitations for repetitive pulses at various case temperatures can be determined by using the thermal response curves. Motorola Application Note, AN569, “Transient Thermal Resistance–General Data and Its Use” provides detailed instructions. The FBSOA curves define the maximum drain–to–source voltage and drain current that a device can safely handle when it is forward biased, or when it is on, or being turned on. Because these curves include the limitations of simultaneous high voltage and high current, up to the rating of the device, they are especially useful to designers of linear systems.

Thermal Response 6 Motorola TMOS Power MOSFET Transistor Device Data MTB15N06E INFORMATION FOR USING THE D2PAK SURFACE MOUNT PACKAGE RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS Surface mount board layout is a critical portion of the total design. The footprint for the semiconductor packages must be the correct size to ensure proper solder connection interface between the board and the package. With the correct pad geometry, the packages will self align when subjected to a solder reflow process. 0.33 8.38 0.08 2.032 0.42 10.66 0.24 6.096 0.04 1.016 0.12 3.05 0.63 17.02 inches mm POWER DISSIPATION FOR A SURFACE MOUNT DEVICE PD = TJ(max) – TA RθJA The values for the equation are found in the maximum ratings table on the data sheet. Substituting these values into the equation for an ambient temperature TA of 25°C, one can calculate the power dissipation of the device. For a D2PAK device, PD is calculated as follows. PD = 150°C – 25°C = 2.5 Watts 50°C/W The 50°C/W for the D2PAK package assumes the use of the recommended footprint on a glass epoxy printed circuit board to achieve a power dissipation of 2.5 Watts. There are other alternatives to achieving higher power dissipation from the surface mount packages. One is to increase the area of the drain pad. By increasing the area of the drain pad, the power Motorola TMOS Power MOSFET Transistor Device Data dissipation can be increased. Although one can almost double the power dissipation with this method, one will be giving up area on the printed circuit board which can defeat the purpose of using surface mount technology. For example, a graph of RθJA versus drain pad area is shown in Figure 15. RθJA , THERMAL RESISTANCE, JUNCTION TO AMBIENT (°C/W) The power dissipation for a surface mount device is a function of the drain pad size. These can vary from the minimum pad size for soldering to a pad size given for maximum power dissipation. Power dissipation for a surface mount device is determined by TJ(max), the maximum rated junction temperature of the die, RθJA, the thermal resistance from the device junction to ambient, and the operating temperature, TA. Using the values provided on the data sheet, PD can be calculated as follows: 70 Board Material = 0.0625″ G–10/FR–4, 2 oz Copper 60 TA = 25°C 2.5 Watts 50 3.5 Watts 40 5 Watts 30 20 0 2 4 6 8 10 A, AREA (SQUARE INCHES) 12 14 16 Figure 15. Thermal Resistance versus Drain Pad Area for the D2PAK Package (Typical) Another alternative would be to use a ceramic substrate or an aluminum core board such as Thermal Clad. Using a board material such as Thermal Clad, an aluminum core board, the power dissipation can be doubled using the same footprint. 7 MTB15N06E SOLDER STENCIL GUIDELINES Prior to placing surface mount components onto a printed circuit board, solder paste must be applied to the pads. Solder stencils are used to screen the optimum amount. These stencils are typically 0.008 inches thick and may be made of brass or stainless steel. For packages such as the SC–59, SC–70/SOT–323, SOD–123, SOT–23, SOT–143, SOT–223, SO–8, SO–14, SO–16, and SMB/SMC diode packages, the stencil opening should be the same as the pad size or a 1:1 registration. This is not the case with the DPAK and D2PAK packages. If one uses a 1:1 opening to screen solder onto the drain pad, misalignment and/or “tombstoning” may occur due to an excess of solder. For these two packages, the opening in the stencil for the paste should be approximately 50% of the tab area. The opening for the leads is still a 1:1 registration. Figure 16 shows a typical stencil for the DPAK and D2PAK packages. The pattern of the opening in the stencil for the drain pad is not critical as long as it allows approximately 50% of the pad to be covered with paste.

Typical Stencil for DPAK and D2PAK Packages SOLDERING PRECAUTIONS The melting temperature of solder is higher than the rated temperature of the device. When the entire device is heated to a high temperature, failure to complete soldering within a short time could result in device failure. Therefore, the following items should always be observed in order to minimize the thermal stress to which the devices are subjected. • Always preheat the device. • The delta temperature between the preheat and soldering should be 100°C or less.* • When preheating and soldering, the temperature of the leads and the case must not exceed the maximum temperature ratings as shown on the data sheet. When using infrared heating with the reflow soldering method, the difference shall be a maximum of 10°C. • The soldering temperature and time shall not exceed 260°C for more than 10 seconds. 8 • When shifting from preheating to soldering, the maximum temperature gradient shall be 5°C or less. • After soldering has been completed, the device should be allowed to cool naturally for at least three minutes. Gradual cooling should be used as the use of forced cooling will increase the temperature gradient and result in latent failure due to mechanical stress. • Mechanical stress or shock should not be applied during cooling. * Soldering a device without preheating can cause excessive thermal shock and stress which can result in damage to the device. * Due to shadowing and the inability to set the wave height to incorporate other surface mount components, the D2PAK is not recommended for wave soldering. Motorola TMOS Power MOSFET Transistor Device Data MTB15N06E TYPICAL SOLDER HEATING PROFILE For any given circuit board, there will be a group of control settings that will give the desired heat pattern. The operator must set temperatures for several heating zones, and a figure for belt speed. Taken together, these control settings make up a heating “profile” for that particular circuit board. On machines controlled by a computer, the computer remembers these profiles from one operating session to the next. Figure 17 shows a typical heating profile for use when soldering a surface mount device to a printed circuit board. This profile will vary among soldering systems but it is a good starting point. Factors that can affect the profile include the type of soldering system in use, density and types of components on the board, type of solder used, and the type of board or substrate material being used. This profile shows temperature versus time.

The two profiles are based on a high density and a low density board. The Vitronics SMD310 convection/infrared reflow soldering system was used to generate this profile. The type of solder used was 62/36/2 Tin Lead Silver with a melting point between 177 –189°C. When this type of furnace is used for solder reflow work, the circuit boards and solder joints tend to heat first. The components on the board are then heated by conduction. The circuit board, because it has a large surface area, absorbs the thermal energy more efficiently, then distributes this energy to the components. Because of this effect, the main body of a component may be up to 30 degrees cooler than the adjacent solder joints.
