PUMH15-QX

Overview

The Nexperia PUMH15-Q is an NPN/NPN Resistor-Equipped Transistor (RET) housed in a SOT363-3 (SC-88) surface-mount package. It integrates two NPN transistors with built-in bias resistors, where R1 and R2 are nominally 4.7 kΩ each. The device supports a maximum collector-emitter voltage of 50 V and an output current capability of 100 mA per transistor. Total power dissipation reaches 300 mW at 25 °C ambient temperature. Qualified under AEC-Q101, it operates within a junction temperature range up to 150 °C.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to reduce component count
• AEC-Q101 qualified for automotive reliability requirements
• Compact SOT363-3 package reduces pick-and-place costs and PCB area

Applications

• Low current peripheral driver circuits
• Control of IC inputs
• Replacement for general-purpose transistors in digital applications

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm if it denotes a distinct tape-and-reel variant or packaging specification compared to the standard 'PUMH15-Q'. Ensure the ordering code matches the required automotive qualification status and package version before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require dual NPN switching with integrated base biasing. The 4.7 kΩ resistor values suit moderate drive currents. Verify that the 50 V breakdown voltage meets system requirements and that the 100 mA current limit accommodates the load specifications without exceeding thermal limits.

Part Context

This part belongs to Nexperia's PUMH series of resistor-equipped double transistors. It serves as a compact alternative to discrete transistor and resistor combinations. The 'Q' suffix indicates automotive qualification compliance. It replaces older versions like the PUMH15 by utilizing the updated SOT363-3 package outline.

Replacement Considerations

Direct replacements include the PUMH15 (non-automotive grade) or other Nexperia RETs with identical 4.7 kΩ bias values such as the PUMH11-Q (10 kΩ) if resistance values allow adjustment. Verify pinout compatibility between SOT363 variants.
