PIMN31F

Overview

The Nexperia PIMN31 is a dual NPN Resistor-Equipped Transistor (RET) housed in a SOT457 (SC-74) TSOP6 surface-mount package. It integrates two NPN transistors with built-in bias resistors, specifically R1 = 1 kΩ and R2 = 10 kΩ. The device supports a maximum 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 at least 70 at 50 mA, a collector-emitter saturation voltage of 0.3 V max, and an off-state input voltage threshold of 0.3 V to 1 V. The component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to reduce external component count
• AEC-Q101 qualified for reliability in automotive environments
• TSOP6 surface-mount package designed for automated pick-and-place assembly

Applications

• Digital logic circuits in automotive and industrial segments
• Switching loads requiring integrated base drive control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct packaging configuration. Confirm that the AEC-Q101 qualification status meets the specific reliability requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component when a compact dual NPN solution with integrated biasing is required. Ensure the 50 V voltage rating and 500 mA current limit align with the circuit design parameters. Consider the SOT457 footprint dimensions during PCB layout planning.

Part Context

This part belongs to Nexperia's family of resistor-equipped double transistors. It serves as the NPN/NPN complement to the PIMP31PA (PNP/PNP) and differs from single-transistor RET variants by providing two isolated switching channels within a single six-lead package.

Replacement Considerations

Direct functional substitutes include the PIMP31PA for complementary PNP/PNP configurations. Verify pinout compatibility and thermal resistance values when replacing with other dual RET devices from different manufacturers.
