PUMD14,115

Overview

The Nexperia PUMD14 is a Resistor-Equipped Transistor (RET) containing an NPN transistor with a built-in 47 kΩ input bias resistor and a complementary PNP general-purpose transistor. Packaged in the SOT363 (SC-88) surface-mount plastic housing, it provides a compact solution for digital logic interfacing. The device supports a maximum collector-emitter voltage of 50 V and a continuous output current of 100 mA per transistor. It features a total power dissipation rating of 200 mW per transistor and 300 mW for the entire device at 25 °C ambient temperature. The component is qualified to AEC-Q101 standards for automotive reliability.

Feature Summary

• Integrated bias resistors simplify circuit design by reducing external component count
• Small SOT363 package footprint reduces pick and place manufacturing costs
• Qualified for automotive applications under AEC-Q101 stress test standards

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the AEC-Q101 qualification aligns with target automotive application requirements. Ensure thermal management strategies account for the specified junction-to-ambient resistance values during operation.

Selection Notes

Select this component when space constraints require combining discrete transistors with biasing networks. The PUMD14 serves as a direct replacement for separate NPN/PNP pairs where one side requires fixed base biasing. Verify that the 47 kΩ internal resistor value meets the specific drive current requirements of the connected load or interface circuit.

Part Context

The PUMD14 belongs to the PUMD series of dual transistor arrays. It complements the PUMB14 (PNP/NPN) and PUMH14 (NPN/NPN) variants within the same SOT363 package family. This series allows designers to maintain consistent board layouts while adjusting transistor polarity configurations for different signal processing needs.

Replacement Considerations

Direct pin-compatible replacements include other RET devices in the SOT363 package from compatible manufacturers, provided electrical parameters such as VCEO and hFE are verified against the datasheet specifications.
