PUMB3H-QX

Overview

The PUMB3H-QX is a dual pre-biased NPN transistor array manufactured by Nexperia USA Inc. It integrates two NPN transistors with internal biasing resistors within a compact SC-88 (SOT-363) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 200 mW. Internal resistor values typically include a base resistor of 47 kΩ and an emitter resistor of 10 kΩ. Designed for high switching speeds, it features a transition frequency of 150 MHz. The component meets AEC-Q101 automotive qualification standards, ensuring reliability in demanding environments.

Feature Summary

• Dual NPN configuration with integrated biasing resistors simplifies circuit design
• AEC-Q101 qualified for automotive electronics applications
• Compact SC-88 package suitable for space-constrained designs

Applications

• Automotive logic level shifting
• General-purpose switching circuits
• Digital signal processing interfaces

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact electrical tolerances and packaging variants. Ensure compatibility with automated pick-and-place equipment due to the small SC-88 footprint. Confirm RoHS compliance status through the manufacturer's latest declaration before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN solution with fixed biasing is required to reduce external component count. Compare transition frequency and saturation voltage requirements against alternative packages like SOT-23-6 if higher current handling is needed. Verify thermal management capabilities given the 200 mW power dissipation limit in the small outline package.

Part Context

This part belongs to Nexperia's range of digital transistors, which combine bipolar junction transistors with on-chip resistors. These arrays are designed to replace multiple discrete components, saving board space and assembly time. The QX suffix indicates automotive-grade qualification under AEC-Q101 standards.

Replacement Considerations

Publicly confirmed substitutes include PUMD3-QX and PUMC3-QX from the same manufacturer family. Verify pinout compatibility and electrical parameter alignment before substitution.
