NHUMD9-QX

Overview

The NHUMD9-QX is a dual pre-biased NPN/PNP bipolar junction transistor (BJT) array manufactured by Nexperia. It integrates internal base resistors to simplify circuit design and reduce component count. The device features an NPN transistor with a collector-emitter voltage of 80 V, a PNP transistor with a collector-emitter voltage of 80 V, and a maximum continuous collector current of 100 mA for each transistor. The unit operates within a temperature range of -55 °C to +150 °C and is housed in a compact SOT-363 (SC-88) surface-mount package. It holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Dual configuration integrating one NPN and one PNP transistor with built-in biasing resistors
• AEC-Q101 qualified for use in demanding automotive electronic environments
• High thermal stability supporting operation up to 150 °C junction temperature

Applications

• Automotive logic switching circuits
• General-purpose digital signal buffering
• Interface driver stages in control modules

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm pinout compatibility and resistor values. Ensure the ordering code matches the required automotive grade specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require dual complementary switching with integrated biasing. Verify that the 80 V breakdown voltage meets the system's peak transient requirements. Confirm that the SOT-363 footprint aligns with the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the intended duty cycle.

Part Context

This part belongs to the Nexperia NHUMD9 series of pre-biased transistors. The 'Q' suffix typically denotes automotive-grade qualification under AEC-Q101 standards. The 'X' suffix indicates reel packaging. This series provides a compact alternative to discrete BJT pairs, reducing assembly complexity in high-volume manufacturing processes.

Replacement Considerations

Check for direct substitutes within the NHUMD9 family or equivalent dual pre-biased arrays from other manufacturers. Verify that any replacement maintains the same SOT-363 pinout and electrical characteristics. Ensure the alternative component also meets AEC-Q101 requirements if used in automotive applications.
