Drain−to−Source Leakage Current versus Voltage http://onsemi.com 3 30 MMSF7P03HD 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 (Dt) are determined by how fast the FET input capacitance can be charged by current from the generator. 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 t = Q/IG(AV) 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) C, CAPACITANCE (pF) 3500 7.0 TJ = 25°C 3000 6.0 2500 5.0 2000 Q1 20 VGS Q2 4.0 1500 Ciss 3.0 1000 500 1.0 Crss VGS 0 VDS 10 20 10 2.0 Coss 0 −10 30 QT 30 Q3 VD 0 5.0 0 TJ = 25°C ID = 7.0 A 10 15 S 0 20 25 30 35 QG, TOTAL GATE CHARGE (nC) VDS, DRAIN−TO−SOURCE VOLTAGE (VOLTS) Figure 8.

Capacitance Variation http://onsemi.com 4 40 , DRAIN−TO−SOURCE VOLTAGE (VOLTS) 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. V 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 VGS, GATE−TO−SOURCE VOLTAGE (VOLTS) 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). 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 9) 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.

Resistive Switching Time Variation versus Gate Resistance DRAIN−TO−SOURCE DIODE CHARACTERISTICS high di/dts. The diode’s negative di/dt during ta is directly controlled by the device clearing the stored charge. However, the positive di/dt during tb is an uncontrollable diode characteristic and is usually the culprit that induces current ringing. Therefore, when comparing diodes, the ratio of tb/ta serves as a good indicator of recovery abruptness and thus gives a comparative estimate of probable noise generated. A ratio of 1 is considered ideal and values less than 0.5 are considered snappy. Compared to ON Semiconductor standard cell density low voltage MOSFETs, high cell density MOSFET diodes are faster (shorter trr), have less stored charge and a softer reverse recovery characteristic. The softness advantage of the high cell density diode means they can be forced through reverse recovery at a higher di/dt than a standard cell MOSFET diode without increasing the current ringing or the noise generated. In addition, power dissipation incurred from switching the diode will be less due to the shorter recovery time and lower switching losses. The switching characteristics of a MOSFET body diode are very important in systems using it as a freewheeling or commutating diode. Of particular interest are the reverse recovery characteristics which play a major role in determining switching losses, radiated noise, EMI and RFI. System switching losses are largely due to the nature of the body diode itself. The body diode is a minority carrier device, therefore it has a finite reverse recovery time, trr, due to the storage of minority carrier charge, QRR, as shown in the typical reverse recovery wave form of Figure 11. It is this stored charge that, when cleared from the diode, passes through a potential and defines an energy loss. Obviously, repeatedly forcing the diode through reverse recovery further increases switching losses. Therefore, one would like a diode with short trr and low QRR specifications to minimize these losses. The abruptness of diode reverse recovery effects the amount of radiated noise, voltage spikes, and current ringing.

Curves are based upon maximum peak junction temperature and a case temperature (TC) of 25°C. Peak repetitive pulsed power limits are determined by using the thermal response data in conjunction with the procedures discussed in AN569, “Transient Thermal Resistance − General Data and Its Use.” Switching between the off−state and the on−state may traverse any load line provided neither rated peak current (IDM) nor rated voltage (VDSS) is exceeded, and that the transition time (tr, tf) does not exceed 10 ms. In addition the total power averaged over a complete switching cycle must not exceed (TJ(MAX) − TC)/(RqJC). A power MOSFET designated E−FET can be safely used in switching circuits with unclamped inductive loads.

Although industry practice is to rate in terms of energy, avalanche energy capability is not a constant. The energy rating decreases non−linearly with an increase of peak current in avalanche and peak junction temperature. Although many E−FETs can withstand the stress of drain−to−source avalanche at currents up to rated pulsed current (IDM), the energy rating is specified at rated continuous current (ID), in accordance with industry custom. The energy rating must be derated for temperature as shown in the accompanying graph (Figure 13). Maximum energy at currents below rated continuous ID can safely be assumed to equal the values indicated. 10 5000 4500 3500 3000 2500 2000 1500 1000 500 0 100 ID = 7.0 A 4000 25 45 65 85 105 125 145 TJ, STARTING JUNCTION TEMPERATURE (°C) VDS, DRAIN−TO−SOURCE VOLTAGE (VOLTS) Figure 12.
