NHUMD9X

Overview

The NHUMD9X is an NPN/PNP Resistor-Equipped double Transistor (RET) from Nexperia, housed in a SOT363 (SC-88) surface-mount package. It integrates one NPN and one PNP transistor with built-in bias resistors: R1 is 10 kΩ and R2 is 47 kΩ. The device supports a maximum collector-emitter voltage of 80 V and a continuous output current of 100 mA per transistor. Transition frequencies are rated at 170 MHz for the NPN section and 150 MHz for the PNP section. Total power dissipation reaches 350 mW, with a DC current gain minimum of 100 at 10 mA and 5 V.

Feature Summary

• Integrates dual transistors with built-in bias resistors to simplify circuit design and reduce component count.
• Qualified for automotive applications under AEC-Q101 standards.
• Provides high breakdown voltage capability suitable for demanding digital switching environments.

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm packaging details such as reel size or tape specifications. Ensure the ordering code matches the required resistor values (R1=10k, R2=47k) and that the SOT363 footprint aligns with the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact NPN/PNP pair with fixed biasing is required for digital interfacing. The 10 kΩ input resistor offers a standard drive impedance. Verify that the 80 V rating exceeds the peak voltages in the application and that the 100 mA current limit accommodates the load requirements without exceeding thermal limits.

Part Context

This part belongs to the NHUMD9 series within the Nexperia RET family. It serves as the NPN/PNP complement to the NHUMB9 (PNP/PNP) and NHUMH9 (NPN/NPN) variants. All share the same SOT363 package and general electrical characteristics, differing primarily in transistor polarity combinations and internal resistor configurations.

Replacement Considerations

Direct functional equivalents include the NHUMD9 (standard reel) and other members of the NHUMD10/13/9 series if different resistor ratios are acceptable. Verify pinout compatibility and thermal resistance characteristics when substituting with generic NPN/PNP pairs requiring external biasing components.
