PUMH20-QX

Overview

The PUMH20-QX is a dual NPN digital transistor manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in base resistors into a single surface-mount package, specifically the UMT (SOT363) configuration. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 300 mW. It operates within an extended temperature range from -65 °C to +150 °C. The component is RoHS compliant and designed for efficient PCB space utilization in compact electronic circuits.

Feature Summary

• Integrates two NPN transistors with pre-biased base resistors in a single compact package
• Utilizes Trench MOSFET or advanced BJT technology for low on-state resistance and fast switching
• Supports logic-level compatibility for direct interfacing with standard logic outputs
• Qualified for automotive applications under AEC-Q101 standards

Applications

• Relay driver circuits
• High-speed line drivers
• Low-side load switches
• General-purpose switching applications

Procurement Notes

Verify the specific suffix QX against the official Nexperia datasheet to confirm packaging details and tape-and-reel specifications. Ensure the ordering part number matches the required UMT/SOT363 package variant. Cross-reference the manufacturer's longevity program for expected availability timelines before finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require dual NPN switching with integrated biasing. The 50 V rating suits low-voltage logic interfaces. Verify that the 100 mA current limit meets load requirements. Consider the SOT363 footprint constraints during PCB layout. Confirm thermal management needs given the 300 mW power dissipation rating in enclosed spaces.

Part Context

This component belongs to Nexperia's portfolio of pre-biased digital transistors designed to simplify circuit design by reducing external component count. The PUMH series typically offers high integration density. The QX suffix likely denotes specific packaging or quality grading variations within the broader PUMH family, requiring datasheet verification for exact mechanical dimensions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Nexperia's official replacement guide or distributor cross-reference tools for verified equivalents. Ensure any alternative maintains the same UMT/SOT363 pinout and electrical ratings.
