PUMD3-QH

Overview

The Nexperia PUMD3-QH is an automotive-grade, dual Resistor-Equipped Transistor (RET) housed in a compact SOT-363 surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with internal biasing resistors. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per transistor. Internal base and emitter resistors are typically 10kΩ each. With a power dissipation rating of 200mW and a minimum DC current gain of 30, it is designed for space-constrained digital switching applications requiring AEC-Q101 qualification.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Integrated dual configuration combining NPN and PNP transistors with bias resistors
• Compact SOT-363 surface-mount packaging for high-density layouts

Applications

• Automotive digital logic interface circuits
• Load switching in vehicle control modules
• Signal level translation in infotainment systems

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm AEC-Q101 automotive qualification status. Ensure the ordering part number matches the required tape-and-reel quantity and pin orientation. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when designing for automotive environments requiring both NPN and PNP switching capabilities within a minimal footprint. The integrated resistor network simplifies circuit design by reducing external component count. Verify that the 50V voltage rating and 100mA current capacity align with the target application's load requirements.

Part Context

This part belongs to the Nexperia PUMD3 series of dual RETs. It serves as the automotive-qualified variant within the family, offering enhanced reliability compared to standard commercial grades while maintaining identical electrical characteristics and pinout compatibility for direct replacement in qualified designs.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified dual RETs in SOT-363 packages from manufacturers such as onsemi or ROHM. Ensure equivalent VCEO, IC, and resistance values are matched. Verify thermal performance and package dimensions to guarantee mechanical fit without redesign.
