BCP55-10-QX

Overview

The Nexperia BCP55-10-QX is an NPN medium power transistor from the BCP55-Q series, housed in a small SOT223 (SC-73) Surface-Mounted Device plastic package. It features a collector-emitter voltage of 60 V and a continuous collector current of 1 A, with a peak collector current capability of 2 A for single pulses up to 1 ms. The device offers three current gain selections; the -10 suffix specifies a DC current gain range of 63 to 160 at VCE = 2 V and IC = 150 mA. Qualified according to AEC-Q101, it supports high power dissipation capabilities suitable for automotive applications.

Procurement Notes

Verify the specific ordering code matches the required gain bin (-10). Confirm the package variant corresponds to the SOT223 footprint. Ensure the application environment meets the AEC-Q101 qualification requirements if used in automotive systems. Check the most recent datasheet revision for any updates to thermal or electrical characteristics before finalizing the design.

Selection Notes

Select this component when a robust NPN transistor with 60 V rating and 1 A current handling is needed in a surface-mount format. The -10 gain bin provides a defined amplification range for consistent circuit performance. Consider the SOT223 package's thermal dissipation limits based on the PCB copper area and ambient temperature conditions during operation.
