PIMP32X

Overview

The PIMP32X is a PNP/PNP Resistor-Equipped double Transistor (RET) housed in an SOT457 (SC-74) plastic surface-mounted package. It features built-in bias resistors with R1 = 2.2 kΩ and R2 = 10 kΩ, providing a ratio of 4.55. The device supports a collector-emitter voltage (VCEO) of -50 V and an output current (IO) of -500 mA per transistor. Total power dissipation is rated at 420 mW for the device and 290 mW per transistor at 25 °C ambient temperature. Key electrical characteristics include a DC current gain (hFE) of 70 minimum at -50 mA and a transition frequency (fT) of 140 MHz typical.

Feature Summary

• Integrates two PNP transistors with built-in bias resistors to simplify circuit design and reduce component count.
• Offers a cost-saving alternative to discrete BC807 series components in digital applications.
• Provides reduced pick and place costs due to compact dual-transistor packaging.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the requested variant matches the standard SC-74 package outline and marking code '4J' as defined in the product data sheet. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when space constraints require replacing multiple discrete transistors and resistors with a single integrated solution. Ensure the application operates within the -50 V collector-emitter voltage limit and does not exceed the 500 mA output current rating per transistor. Verify thermal management requirements against the specified junction-to-ambient thermal resistance values for the intended PCB footprint.

Part Context

This device belongs to Nexperia's family of resistor-equipped transistors, designed to replace discrete resistor-transistor networks. It serves as the PNP/PNP complement to the NPN/NPN PIMN32 and the NPN/PNP PIMC32 variants. The component utilizes the SOT457 package to maintain a small footprint while delivering dual switching functionality with integrated base biasing.

Replacement Considerations

Direct functional replacements include the PIMN32 for NPN/NPN configurations and the PIMC32 for NPN/PNP combinations. Verify pin compatibility and electrical ratings when substituting with other RET families. Ensure the alternative component meets the same SC-74 package dimensions and thermal performance specifications.
