PUMD20/ZLX

Overview

The Nexperia PUMD20 is a dual Resistor-Equipped Transistor (RET) containing one NPN and one PNP transistor in a TSSOP6 (SOT363-3) surface-mount package. It features built-in bias resistors with nominal values of R1 = 2.2 kΩ and R2 = 2.2 kΩ per transistor. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and an output current (IO) of 100 mA per transistor. Total power dissipation is rated at 200 mW per transistor and 300 mW for the complete device at ambient temperatures up to 25 °C. The junction temperature limit is 150 °C, and it operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Replacement of general purpose transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and manufacturing site code. Confirm that the requested variant matches the standard product data sheet specifications before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require complementary NPN/PNP switching with integrated base drive. Ensure the required input impedance aligns with the 2.2 kΩ nominal bias resistor value. Verify thermal management requirements against the 200 mW per-transistor dissipation limit under expected operating conditions.

Part Context

This part belongs to the PUMD series of dual resistor-equipped transistors. Complementary configurations include the PUMH20 (NPN/NPN) and PUMB20 (PNP/PNP). All variants share similar electrical characteristics but differ in internal transistor polarity combinations to suit specific logic interface needs.

Replacement Considerations

Direct replacements must match the SOT363-3 footprint and provide equivalent 50 V / 100 mA ratings with comparable bias resistor values. Verify pinout compatibility and thermal resistance characteristics to ensure seamless integration without PCB layout modifications.
