PUMD9-QF

Overview

The PUMD9-QF is a resistor-equipped double transistor (RET) from Nexperia, featuring one NPN and one PNP transistor in a single SOT363 (SC-88/TSSOP-6) package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes built-in bias resistors: R1 is typically 10 kOhms and R2 is typically 47 kOhms. It offers a DC current gain (hFE) minimum of 100 at 5 mA/5 V. Transition frequencies are rated at 230 MHz for the NPN and 180 MHz for the PNP sections. Power dissipation is limited to 200 mW.

Feature Summary

• Integrates complementary NPN and PNP transistors with pre-biasing resistors to reduce component count and simplify circuit design.
• Qualified according to AEC-Q101 standards, making it suitable for demanding automotive applications.
• Utilizes a compact SOT363 surface-mount package to support high-density PCB layouts.

Applications

• Digital logic interfaces in automotive and industrial segments
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'QF' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure that the ordering information matches the required tape-and-reel specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Selection Notes

Select this component when a dual transistor solution with integrated biasing is required for space-constrained designs. The PUMD9-QF serves as a cost-saving alternative to discrete resistor-transistor combinations. Consider its 50V rating and 100mA current capability to ensure compatibility with the target load requirements.

Part Context

This part belongs to the PUMD9 family of resistor-equipped double transistors. It complements other variants such as the PUMH9-Q (NPN/NPN) and PUMB9-Q (PNP/PNP). The Q-series designation indicates automotive qualification under AEC-Q101 standards, distinguishing it from standard commercial grade components within the same electrical specification range.

Replacement Considerations

Direct substitutes include PUMD9-QX and PUMD9,115, which share identical electrical characteristics and pin configurations. Verify that any replacement maintains the same SOT363 footprint and AEC-Q101 qualification if automotive reliability is required.
