PUMB3HF

Overview

The PUMB3HF is a dual PNP resistor-equipped transistor (RET) from Nexperia, housed in an SOT363 (TSSOP6) surface-mount package. It integrates two PNP bipolar junction transistors with built-in biasing resistors to simplify circuit design and reduce component count. The device is rated for a collector-emitter voltage of -50 V and supports an output current of -100 mA per transistor. This pre-biased configuration ensures stable switching performance while minimizing external passive components required for base drive control.

Feature Summary

• Integrates dual PNP transistors with built-in biasing resistors
• Designed for simplified switching applications with reduced external component count
• Utilizes SOT363 surface-mount packaging for compact board space

Applications

• General-purpose switching circuits
• Logic level translation interfaces
• Driver stages for low-current loads

Procurement Notes

Verify the specific ordering code suffix to ensure compatibility with required tape-and-reel or cut-tape packaging formats. Confirm that the -50 V rating and -100 mA current limits align with the target application's electrical requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual PNP solution with integrated base resistors is required to minimize PCB area. Ensure the application does not exceed the -100 mA per transistor limit. Consider thermal dissipation capabilities within the SOT363 package if operating near maximum current ratings continuously.

Part Context

This part belongs to Nexperia’s portfolio of resistor-equipped transistors (RETs), which combine discrete transistors with precision resistors in a single package. These devices are designed to replace multiple discrete components, offering cost savings and improved reliability in digital switching and logic interface applications.

Replacement Considerations

Direct substitutes may include other dual PNP RETs in compatible packages such as SOT363. Verify pinout compatibility and electrical parameters like VCEO and IC to ensure functional equivalence without redesigning the surrounding circuitry.
