PUMH9-QX

Overview

The PUMH9-QX is a dual NPN resistor-equipped transistor (RET) from Nexperia, designed for compact surface-mount applications. It features an integrated base resistor of 10 kOhm and an emitter resistor of 47 kOhm. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. With a power dissipation rating of 300mW, it operates within a temperature range of -55°C to +150°C. Packaged in the SOT363-3 (SC-88) format, this automotive-grade component ensures reliable performance in space-constrained circuit designs requiring pre-biased switching capabilities.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability
• Integrated biasing resistors simplify circuit design by reducing external component count
• Compact SOT363-3 package enables high-density PCB layouts

Applications

• Automotive body control modules
• General-purpose logic level switching
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and tape-and-reel specifications. Ensure that the automotive grade designation aligns with project requirements for AEC-Q101 compliance. Cross-reference the full part number with authorized distributors to confirm availability and lead times for production runs.

Selection Notes

Select the PUMH9-QX when space constraints necessitate a dual NPN configuration with integrated biasing. The automotive qualification makes it suitable for harsh environments where standard commercial parts may fail. Compare the 10k/47k resistor values against other RET variants like PUMH9 or PUMB9 to ensure impedance matching for the specific application load.

Part Context

This component belongs to Nexperia's Resistor-Equipped Transistor (RET) family, specifically the PUMH series. It serves as the NPN/NPN variant within this lineup, offering a complement to PNP/PNP types like the PUMB9. The 'Q' suffix indicates automotive qualification, distinguishing it from standard commercial versions while maintaining identical electrical characteristics and pinout compatibility.

Replacement Considerations

Direct substitutes include the non-automotive PUMH9 for general use. For complementary functions, consider the PNP/PNP PUMB9 or the NPN/PNP PUMD9. Verify that any replacement maintains the same SOT363 footprint and internal resistor values to ensure seamless integration without schematic modifications.
