PIMC31,115

Overview

The PIMC31 is a double Resistor-Equipped Transistor (RET) containing one NPN and one PNP transistor in a TSOP6 (SOT457) package. It supports a collector-emitter voltage of 50 V and an output current of 500 mA per transistor. The device integrates a 1 kΩ input bias resistor (R1) and a 10 kΩ feedback resistor (R2), yielding a nominal R2/R1 ratio of 10. Total power dissipation reaches 420 mW at 25 °C ambient temperature, with a junction temperature limit of 150 °C. DC current gain is specified at a minimum of 70 at 50 mA.

Feature Summary

• Integrates dual NPN/PNP transistors with built-in bias resistors to simplify circuit design
• Reduces component count and pick-and-place costs by combining active and passive elements
• Provides high output current capability suitable for digital switching applications

Applications

• Digital applications in automotive and industrial segments
• Switching loads
• Controlling IC inputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and marking codes. Confirm that the selected variant meets the required thermal and electrical specifications for the target application environment. Ensure compliance with RoHS directives if applicable to the manufacturing process.

Selection Notes

Select this component when space-saving dual transistor solutions are required for digital logic interfacing. The integrated bias network eliminates external resistor placement. Verify that the 50 V voltage rating and 500 mA current capacity align with the load requirements. Consider the SOT457 footprint constraints during PCB layout planning.

Part Context

The PIMC31 belongs to Nexperia's family of Resistor-Equipped Transistors (RETs). It serves as the NPN/PNP complement to the PIMN31 (NPN/NPN) and PIMP31 (PNP/PNP) variants. These devices are designed to replace multiple discrete components in digital switching circuits, offering a compact alternative to standard bipolar arrays.

Replacement Considerations

Direct functional substitutes include the PIMN31 for NPN/NPN configurations or the PIMP31 for PNP/PNP setups within the same package. Cross-reference pinouts and resistor values carefully when replacing with other RET families to ensure compatibility with existing bias networks.
