PUMH24-QX

Overview

The PUMH24-QX is an NPN/NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in bias resistors, each having a typical resistance of 100 kOhm. The device is housed in a compact SOT363-3 (SC-88) surface-mount package, measuring 2.1 x 1.25 x 0.95 mm. It supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The total power dissipation is rated at 300 mW, with a maximum junction temperature of 150 °C. This component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Integrates dual NPN transistors with fixed 100 kOhm bias resistors to simplify circuit design
• AEC-Q101 qualified for robust performance in automotive environments
• Compact SOT363-3 package reduces component count and pick-and-place costs

Applications

• Low current peripheral driver circuits
• Control of IC inputs in digital logic systems
• Replacement for general-purpose discrete transistors in space-constrained designs

Procurement Notes

Verify the specific suffix '-QX' against official Nexperia documentation to confirm it denotes the same electrical characteristics as the standard PUMH24 part number. Confirm that the AEC-Q101 qualification status applies to this specific variant. Ensure compatibility with required packaging formats such as cut tape or reel before finalizing procurement orders.

Selection Notes

Select the PUMH24-QX when a dual NPN configuration with integrated biasing is required for digital switching or input control. The 100 kOhm resistor values are suitable for standard logic levels. Consider the SOT363-3 footprint constraints during PCB layout. Verify thermal management requirements given the 300 mW power dissipation limit in enclosed spaces.

Part Context

The PUMH24-QX belongs to Nexperia's family of Resistor-Equipped Transistors (RETs). It serves as the NPN/NPN complement to the PUMD24 (NPN/PNP) and PUMB24 (PNP/PNP) variants. These devices are designed to replace multiple discrete components, reducing board space and assembly complexity in modern electronic systems.

Replacement Considerations

Direct functional equivalents include the PUMH24 (standard commercial grade) if automotive qualification is not strictly required. For complementary configurations, consider PUMD24 for NPN/PNP needs. Always verify pinout compatibility and exact resistor tolerances before substituting.
