Overview
The Nexperia PUMD48 is a Resistor-Equipped Transistor (RET) double transistor featuring one NPN and one PNP unit in a TSSOP6 (SOT363-3) package. It provides a collector-emitter voltage of 50 V and an output current capability of 100 mA per transistor. The device integrates bias resistors: TR1 (NPN) includes R1 = 47 kΩ and R2 = 47 kΩ, while TR2 (PNP) includes R1 = 2.2 kΩ and R2 = 47 kΩ. Total power dissipation is rated at 300 mW at 25 °C ambient temperature.
