MUN5316DW1T1

Overview

The MUN5316DW1T1G is a dual Bias Resistor Transistor (BRT) from the MUN5311DW1T1 series, manufactured by onsemi. It integrates an NPN and a PNP silicon surface mount transistor with monolithic bias resistor networks into a single SOT-363 package. The device features a series base resistor (R1) of 4.7 kΩ and no base-emitter resistor (R2). Maximum ratings include a collector-base voltage (VCBO) and collector-emitter voltage (VCEO) of 50 Vdc, and a collector current (IC) of 100 mAdc. Thermal characteristics specify a total device dissipation of 187 mW at 25°C for one junction heated, with a thermal resistance (RθJA) of 670 °C/W.

Feature Summary

• Integrates complementary NPN and PNP transistors with monolithic bias resistor networks to replace individual devices and external resistors.
