BCP54-10T-QF

Overview

The BCP54-10T-QF is an NPN power bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. It is housed in a SOT223 (SC-73) surface-mount package and designed for high-current applications with a maximum collector current of 1 A. The device features a collector-emitter voltage rating of 45 V and a collector-base voltage of 45 V, with an emitter-base voltage limit of 5 V. It offers a power dissipation capability of 800 mW at 25°C ambient temperature and a DC current gain range of 100 to 250 for the -10 variant. The component is qualified under the AEC-Q101 standard for automotive reliability.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• High collector current capability suitable for power switching
• Three distinct current gain selections available within the series
• Surface-mount construction in a compact SOT223 plastic package

Applications

• Linear voltage regulators
• MOSFET drivers
• Low-side switches
• Power management circuits
• Amplifiers

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm it denotes the correct AEC-Q101 automotive grade and the '-10' current gain bin. Ensure the ordering part number matches the required SOT223 package configuration. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when an NPN transistor with 1 A continuous current handling and 45 V blocking voltage is required in a surface-mount format. The -10 gain bin provides a specific amplification range suitable for linear regulation or driver stages. Consider thermal management requirements due to the 800 mW dissipation limit in the SOT223 package.

Part Context

This part belongs to the BCX54/BCP54 family of NPN power transistors from Nexperia. While the BCX54 series utilizes the SOT89 package, the BCP54 variant specifically employs the SOT223 outline. Both families share similar electrical characteristics but differ in physical footprint and thermal performance capabilities.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified NPN transistors in the SOT223 package with matching 45 V / 1 A ratings. Verify that replacement parts offer comparable hFE ranges and power dissipation limits to ensure circuit compatibility.
