PIMN32X

Overview

The Nexperia PIMN32X is a NPN/NPN Resistor-Equipped double Transistor (RET) housed in an SOT457 (SC-74) surface-mounted plastic package. It features two integrated NPN transistors with built-in bias resistors, specifically R1 at 2.2 kΩ and R2 at 10 kΩ. The device supports a collector-emitter voltage of 50 V and delivers an output current capability of 500 mA per transistor. Key electrical characteristics include a DC current gain (hFE) of 70 at 50 mA, a transition frequency (fT) of 225 MHz, and a total power dissipation of 420 mW for the dual device configuration.

Feature Summary

• Integrates two NPN transistors with fixed internal bias resistors to simplify circuit design
• Provides high output current capability suitable for driving loads directly
• Reduces component count and assembly costs through single-package integration

Applications

• Digital logic applications requiring signal buffering or level shifting
• Cost-effective replacement for discrete BC817 series transistor pairs
• Control interfaces for IC inputs
• General-purpose load switching circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm packaging type and reel specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target application environment before finalizing procurement orders.

Selection Notes

Select this component when space constraints favor a six-lead SC-74 package over discrete transistor arrangements. Ensure the required input resistance matches the fixed 2.2 kΩ value. Verify that the 50 V collector-emitter voltage rating exceeds the maximum operating voltage of the target circuit to maintain reliable performance margins.

Part Context

The PIMN32X belongs to Nexperia's family of resistor-equipped double transistors designed to replace multiple discrete components. Its complement includes the PNP/PNP variant PIMP32 and the NPN/PNP variant PIMC32. This specific part number denotes the standard production version without automotive-specific qualification suffixes.

Replacement Considerations

Direct functional substitutes include the PIMP32 for complementary polarity needs and the PIMC32 for mixed NPN/PNP configurations. Discrete BC817 transistor pairs may serve as manual replacements but require additional board space and external biasing components.
