PUMD48-QX

Overview

The PUMD48-Q is an NPN/PNP double Resistor-Equipped Transistor (RET) housed in a SOT363-3 (SC-88) surface-mounted device plastic package. It features a 50 V collector-emitter voltage rating and a 100 mA output current capability per transistor. The NPN transistor (TR1) includes a typical input bias resistor of 47 kΩ, while the PNP transistor (TR2) has a typical input bias resistor of 2.2 kΩ. Both transistors share a common R2 bias resistor value of 47 kΩ. The device is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Reduces pick and place costs by replacing multiple discrete components with a single package.
• Qualified according to AEC-Q101 standards for use in automotive applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant and marking code. Confirm that the selected part number aligns with the required AEC-Q101 qualification status for your target application environment. Ensure compatibility with standard reflow soldering profiles specified for the SOT363-3 package.

Selection Notes

Select this component when space constraints require combining two transistors with integrated base resistors into one footprint. Verify that the 50 V breakdown voltage and 100 mA current limits meet the circuit requirements. Consider the specific resistor values (47 kΩ for NPN, 2.2 kΩ for PNP) to ensure proper biasing without external components.

Part Context

This device belongs to Nexperia's family of double Resistor-Equipped Transistors designed to minimize PCB area. It combines an NPN and a PNP transistor within a single SOT363-3 package, offering a compact solution for digital logic interfacing and switching tasks where discrete resistor integration would otherwise increase assembly complexity.

Replacement Considerations

Direct substitutes include other NPN/PNP RETs in the SOT363-3 package with similar electrical ratings. Verify pinout compatibility and resistor tolerance specifications before substitution. Check for equivalent AEC-Q101 qualification if automotive reliability is required.
