BCP56TF

Overview

The BCP56TF is a single NPN silicon bipolar junction transistor manufactured by Nexperia. It is housed in a SOT-223 (SC-73) surface-mount package designed for high-performance switching and amplification applications. The device supports a maximum continuous collector current of 1 A and withstands a collector-emitter voltage of 80 V. Key electrical characteristics include a collector-base voltage rating of 100 V, an emitter-base voltage limit of 5 V, and a power dissipation capacity of 960 mW. The component exhibits a DC current gain (hFE) of at least 100 when tested at 150 mA with a collector-emitter voltage of 2 V.

Feature Summary

• High current handling capability suitable for moderate-power switching tasks
• Robust voltage ratings providing reliable operation in standard logic and analog circuits
• Surface-mount construction optimized for automated PCB assembly processes

Applications

• General-purpose switching circuits
• Amplifier stages requiring moderate gain
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix 'TF' against the official Nexperia datasheet to confirm tape-and-reel packaging specifications and binning grades. Ensure the ordering part number matches the required hFE range and thermal characteristics. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and recommended soldering profiles for the SOT-223 package prior to final procurement.

Selection Notes

Select this component when a single NPN transistor with 1 A current capacity and 80 V breakdown voltage is required in a compact surface-mount form factor. The SOT-223 package offers superior thermal performance compared to smaller packages like SOT-23, making it suitable for applications where heat dissipation is a constraint. Verify that the required current gain meets the minimum threshold specified in the circuit design.

Part Context

This component belongs to the BC56 series of NPN transistors from Nexperia, which are widely used in consumer electronics and industrial equipment. The series provides a balance of performance and cost-effectiveness for general-purpose applications. The BCP56 variant specifically utilizes the SOT-223 package to handle higher power dissipation than standard small-signal transistors, bridging the gap between low-power devices and larger power transistors.

Replacement Considerations

Direct replacements must match the NPN polarity, 1 A current rating, and 80 V voltage rating in a SOT-223 package. Verify pinout compatibility and thermal resistance values before substitution.
