PUMH14-QX

Overview

The Nexperia PUMH14-QX is a dual NPN Resistor-Equipped Transistor (RET) housed in a SOT363 (SC-88) TSSOP6 surface-mount package. It integrates two NPN transistors with built-in bias resistors, where R1 is specified at 47 kΩ and R2 remains open. The device supports a maximum collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Total power dissipation reaches 300 mW for the device and 200 mW per transistor at 25 °C ambient temperature. It operates within a junction temperature range up to 150 °C and is qualified under AEC-Q101 standards.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• AEC-Q101 qualification ensures suitability for automotive applications
• Compact SOT363 plastic package reduces pick and place costs

Applications

• Low current peripheral driver
• Controlling IC inputs
• Replacement of general purpose transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the procurement channel provides valid traceability records consistent with automotive-grade quality requirements. Confirm that the delivered components match the exact part number designation to avoid functional discrepancies in final assembly.

Selection Notes

Select this component when a compact dual NPN solution with integrated biasing is required for space-constrained designs. The fixed 47 kΩ input resistor eliminates external bias network calculations. Verify that the open R2 configuration aligns with the intended logic interface requirements. Consider the thermal derating characteristics if operating near the upper ambient temperature limits.

Part Context

This device belongs to the PUMH series of NPN/NPN resistor-equipped transistors from Nexperia. It serves as a specialized discrete semiconductor alternative to standard general-purpose transistors, offering simplified integration for digital control circuits. The QX suffix typically denotes a specific manufacturing or packaging variant within the broader PUMH family.

Replacement Considerations

Direct replacements include other Nexperia RETs with similar configurations, such as the PUMH11-Q or PUMH12-Q, provided their internal resistor values match the circuit requirements. Cross-manufacturer equivalents must be verified for identical pinout, voltage ratings, and current capabilities.
