PIMP31PAX

Overview

The PIMP31PAX is a PNP/PNP Resistor-Equipped double Transistor (RET) manufactured by Nexperia, housed in a DFN2020-6 (SOT1118) leadless surface-mounted package. It features built-in bias resistors with R1 = 1 kΩ and R2 = 10 kΩ. The device supports a collector-emitter voltage of -50 V and an output current of -500 mA per transistor. Key electrical characteristics include a DC current gain (hFE) of 70 at -50 mA, a transition frequency (fT) of 150 MHz, and a collector-base cut-off current of -100 nA. The junction temperature range extends from -55 °C to 150 °C.

Feature Summary

• Integrates dual PNP transistors with built-in bias resistors to simplify circuit design and reduce component count.
• Provides high output current capability suitable for driving loads and controlling IC inputs.
• Utilizes a compact, leadless thermal-enhanced plastic package to minimize PCB footprint and placement costs.

Applications

• Digital logic applications
• Cost-saving alternative to BC807 series in digital circuits
• Control of integrated circuit inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix 'X' against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee product authenticity and traceability. Confirm that the delivered components match the DFN2020-6 package outline and marking code '8G' specified in the datasheet.

Selection Notes

Select this component when a dual PNP configuration with fixed bias resistors is required for space-constrained designs. Compare the 500 mA current rating and 50 V voltage limits against application requirements. Consider the SOT1118 package dimensions for PCB layout compatibility. Evaluate thermal resistance values based on the intended PCB copper area and layer configuration to ensure adequate heat dissipation.

Part Context

The PIMP31PA belongs to Nexperia's family of Resistor-Equipped Transistors (RETs). Complementary variants include the NPN/NPN type PIMN31PA and the NPN/PNP type PIMC31PA. These devices share similar performance profiles but differ in transistor polarity configurations, allowing designers to choose the appropriate type for specific circuit topologies while maintaining consistent packaging and integration benefits.

Replacement Considerations

Direct functional substitutes within the same RET family include PIMN31PA for NPN/NPN configurations and PIMC31PA for NPN/PNP combinations. Verify pinout compatibility and electrical parameters before substituting with general-purpose discrete transistors, as external resistor networks will be required in those cases.
