BCP54-16,135

Overview

The BCP54-16,135 is an NPN medium power transistor from the Nexperia BCP54 series, housed in a SOT223 (SC-73) flat lead Surface-Mounted Device plastic package. It features a collector-emitter voltage of 45 V and a continuous collector current capability of 1 A, with a peak collector current of 2 A for single pulses up to 1 ms. The device offers three current gain selections; the -16 variant provides a DC current gain range of 100 to 250 at VCE = 2 V and IC = 150 mA. It is qualified to the AEC-Q101 standard for automotive applications.

Procurement Notes

Verify the specific ordering suffix matches the required quantity per reel or tape-and-reel configuration. Confirm the package type corresponds to the SOT223 footprint requirements for your PCB design. Ensure the current gain bin (-16) aligns with circuit beta requirements. Check the most recent datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a medium power NPN transistor with high current handling is required in a surface-mount format. The -16 gain bin is appropriate for designs needing a hFE range of 100 to 250. Consider the SOT223 package's thermal performance relative to your PCB copper area, as power dissipation varies significantly with mounting pad size. Verify that the 45 V rating exceeds the maximum operating voltage in your application.

Part Context

The BCP54-16,135 belongs to the BCP54 series of NPN medium power transistors manufactured by Nexperia. This series includes variants with different current gain ranges, specifically the BCP54, BCP54-10, and BCP54-16. All share the same electrical limits and package but differ in hFE classification. The series is designed for general-purpose switching and amplification tasks in consumer and automotive electronics.

Replacement Considerations

Direct substitutes within the same family include the BCP54 and BCP54-10, provided their respective current gain ranges meet the circuit design specifications. Other NPN transistors in the SOT223 package may be considered if pinout compatibility and electrical ratings are verified against the BCP54-16 datasheet parameters.
