BCP53HX

Overview

The Nexperia BCP53HX is a single PNP bipolar junction transistor (BJT) designed for surface-mount applications. It utilizes the SOT-223 (SC-73) three-terminal package and operates on silicon technology. The device supports a maximum continuous collector current of 1 A, with a collector-emitter voltage rating of 80 V and a collector-base voltage of 100 V. Key electrical characteristics include a transition frequency of 140 MHz, a power dissipation capacity of 2.2 W, and an emitter-base voltage limit of 7 V. The component functions within a temperature range from -55°C to +175°C.

Feature Summary

• High thermal stability enabling operation up to 175°C
• Robust 1 A current handling capability in a compact surface-mount footprint
• Integrated heat-sinking tab design for efficient power dissipation

Applications

• General-purpose switching circuits
• Power management modules
• Driver stages for loads requiring moderate current

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact binning and packaging specifications. Ensure the procurement channel provides traceable datasheets matching the SC-73 package designation. Confirm RoHS compliance status directly through manufacturer records prior to integration into regulated assemblies.

Selection Notes

Select this component when high-temperature reliability and substantial power dissipation are required in a surface-mount format. The SOT-223 package offers superior thermal performance compared to smaller alternatives like SOT-23. Evaluate the 80 V collector-emitter voltage rating against circuit peak voltages to ensure adequate safety margins during transient conditions.

Part Context

This part belongs to the BCP53 series of high-performance PNP transistors manufactured by Nexperia. The series is engineered for general-purpose applications requiring reliable switching and amplification. The HX variant specifically denotes the SOT-223 package configuration, distinguishing it from other form factors within the same electrical family.

Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Cross-reference pinouts and thermal resistance values when considering alternative manufacturers.
