MUN5311DW1T1 Series Preferred Devices Dual Bias Resistor Transistors NPN and PNP Silicon Surface Mount Transistors with Monolithic Bias Resistor Network http://onsemi.com The BRT (Bias Resistor Transistor) contains a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base–emitter resistor. These digital transistors are designed to replace a single device and its external resistor bias network. The BRT eliminates these individual components by integrating them into a single device. In the MUN5311DW1T1 series, two complementary BRT devices are housed in the SOT–363 package which is ideal for low power surface mount applications where board space is at a premium. • • • • (3) (2) R1 Q2 R2 R1 (4) (5) (6) 6 5 4 1 MAXIMUM RATINGS (TA = 25°C unless otherwise noted, common for Q1 Symbol Value Unit Collector-Base Voltage VCBO 50 Vdc Collector-Emitter Voltage VCEO 50 Vdc IC 100 mAdc Symbol Max Unit PD 187 (Note 1.) 256 (Note 2.) 1.5 (Note 1.) 2.0 (Note 2.) mW 2 3 SOT–363 CASE 419B STYLE 1 and Q2, – minus sign for Q1 (PNP) omitted) Collector Current R2 Q1 Simplifies Circuit Design Reduces Board Space Reduces Component Count Available in 8 mm, 7 inch/3000 Unit Tape and Reel Rating (1) MARKING DIAGRAM THERMAL CHARACTERISTICS Characteristic (One Junction Heated) xx Total Device Dissipation TA = 25°C Derate above 25°C Thermal Resistance – Junction-to-Ambient Characteristic (Both Junctions Heated) mW/°C = Device Marking = (See Page 2) RθJA 670 (Note 1.) 490 (Note 2.) °C/W Symbol Max Unit DEVICE MARKING INFORMATION mW See specific marking information in the device marking table on page 2 of this data sheet.

The footprint for the semiconductor packages must be the correct size to insure 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. SOT–363 ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ 0.65 mm 0.65 mm 0.4 mm (min) 0.5 mm (min) 1.9 mm SOT–363 POWER DISSIPATION one can calculate the power dissipation of the device which in this case is 256 milliwatts. The power dissipation of the SOT–363 is a function of the pad size. This can vary from the minimum pad size for soldering to the 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: PD = PD = 150°C – 25°C = 256 milliwatts 490°C/W The 490°C/W for the SOT–363 package assumes the use of the recommended footprint on a glass epoxy printed circuit board to achieve a power dissipation of 256 milliwatts. There are other alternatives to achieving higher power dissipation from the SOT–363 package. 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. 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, SOLDERING PRECAUTIONS • The soldering temperature and time should not exceed 260°C for more than 10 seconds. • When shifting from preheating to soldering, the maximum temperature gradient should 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. 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 should be a maximum of 10°C. * Soldering a device without preheating can cause excessive thermal shock and stress which can result in damage to the device. http://onsemi.com 14 MUN5311DW1T1 Series SOLDER STENCIL GUIDELINES or stainless steel with a typical thickness of 0.008 inches. The stencil opening size for the surface mounted package should be the same as the pad size on the printed circuit board, i.e., a 1:1 registration. Prior to placing surface mount components onto a printed circuit board, solder paste must be applied to the pads. A solder stencil is required to screen the optimum amount of solder paste onto the footprint. The stencil is made of brass TYPICAL SOLDER HEATING PROFILE The line on the graph shows the actual temperature that might be experienced on the surface of a test board at or near a central solder joint. 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. 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 46 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.
