PIMC31PAX

Overview

The PIMC31PAX is a Resistor-Equipped double Transistor (RET) manufactured by Nexperia USA Inc., featuring one NPN and one PNP transistor in a DFN2020-6 (SOT1118) leadless surface-mount package. It provides a collector-emitter voltage of 50 V and an output current capability of 500 mA per transistor. The device integrates bias resistors with R1 at 1 kΩ and R2 at 10 kΩ, simplifying circuit design. Key electrical characteristics include a DC current gain (hFE) minimum of 70 at 50 mA and 5 V, and a collector-emitter saturation voltage maximum of 100 mV at 50 mA. Transition frequencies are specified at 210 MHz for the NPN and 150 MHz for the PNP transistor.

Feature Summary

• Integrates NPN and PNP transistors with built-in bias resistors to reduce component count
• Supports 500 mA output current capability for switching applications
• Utilizes a leadless DFN2020-6 package for thermal efficiency and space savings

Applications

• Digital logic circuits
• Control of IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix 'X' against official Nexperia documentation to confirm tape-and-reel specifications or marking codes. Confirm RoHS compliance status and ensure the DFN2020-6 footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a mixed NPN/PNP configuration with integrated base resistors is required. The 1 kΩ input resistor and 10 kΩ feedback resistor ratio suit standard digital interface levels. Ensure thermal management accounts for the 360 mW power dissipation limit in free air conditions.

Part Context

This part belongs to the PIMC31 family of resistor-equipped double transistors. Complementary variants include the PIMN31PA (NPN/NPN) and PIMP31PA (PNP/PNP). All share similar electrical ratings but differ in transistor polarity configurations within the same SOT1118 package.

Replacement Considerations

Publicly confirmed substitutes include PIMN31PA and PIMP31PA from Nexperia, which share the same package and general rating profile but offer different internal transistor polarities.
