PUMD16/ZLX

Overview

The PUMD16/ZLX is an NPN/PNP resistor-equipped transistor array manufactured by Nexperia USA Inc. in a SOT363 (SC-88) surface-mount package. It integrates one NPN and one PNP transistor with built-in bias resistors, where R1 is nominally 22 kΩ and R2 is 47 kΩ. The device supports a maximum collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Total power dissipation is rated at 300 mW at 25 °C ambient temperature. The DC current gain (hFE) is typically 80 at 5 mA collector current.

Feature Summary

• Integrates NPN and PNP transistors with built-in bias resistors to simplify circuit design
• Reduces component count and pick-and-place costs through compact packaging
• Features low package height for space-constrained applications

Applications

• Low current peripheral driver
• Control of IC inputs
• Replacement of general-purpose transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm tape-and-reel specifications and marking codes. Confirm RoHS compliance status and ensure the selected variant matches the required SOT363 package dimensions for PCB footprint compatibility during procurement.

Selection Notes

Select this component when a matched NPN/PNP pair with fixed biasing is required for digital switching or input buffering. Ensure the 50 V collector-emitter voltage rating exceeds the application's peak voltage. Verify that the 100 mA output current capability meets the load requirements and that the 300 mW power dissipation limit is sufficient for the thermal environment.

Part Context

The PUMD16 belongs to the PEMD16/PUMD16 family of NPN/PNP resistor-equipped transistors. The PUMD16 variant specifically utilizes the SOT363 (SC-88) package, while the PEMD16 uses the SOT666 package. Both share identical electrical characteristics but differ in physical footprint and pinout orientation.

Replacement Considerations

Publicly documented complements include PUMB16 (PNP/PNP) and PUMH16 (NPN/NPN). Direct replacements must match the SOT363 package and the 22 kΩ/47 kΩ resistor configuration.
