PUMB2-QX

Overview

The PUMB2-QX is a dual pre-biased NPN bipolar junction transistor (BJT) array manufactured by Nexperia. It integrates two NPN transistors with built-in biasing resistors within a compact SOT-363 (SC-88) surface-mount package. The device is rated for a collector-emitter voltage of -50 V and a continuous collector current of -100 mA, with a total power dissipation of 200 mW. Designed for automotive applications, it complies with the AEC-Q101 qualification standard, ensuring reliability under stringent environmental conditions.

Feature Summary

• Dual integrated NPN transistors with embedded biasing resistors to simplify circuit design
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SOT-363 surface-mount package for space-constrained applications

Applications

• Automotive electronic control units
• General-purpose switching in automotive systems
• Signal conditioning circuits requiring isolated biasing

Procurement Notes

Verify the specific ordering code suffix against the official Nexperia datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the requested variant matches the required electrical characteristics and packaging format for your production line.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in an automotive environment. The SOT-363 package offers a small footprint suitable for dense PCB layouts. Consider the 50V rating and 100mA current limit to ensure adequate headroom for the intended load. Verify compatibility with the system's thermal management constraints given the 200mW power dissipation rating.
