BC857BW-QX

Overview

The BC857BW-QX is a PNP general-purpose transistor manufactured by Nexperia, designed for surface-mount applications in the SOT363 (SC-88) package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device is qualified to AEC-Q101 standards for automotive reliability, supporting an operating temperature range from -55 °C to +175 °C with a total power dissipation of 400 mW. Its DC current gain ranges from 200 to 450, and it offers a transition frequency of 100 MHz.

Feature Summary

Automotive-grade qualification compliant with AEC-Q101 standards
Ultra-small SOT363 leadless plastic package design
High thermal stability with extended operating temperature limits

Applications

General purpose switching circuits in automotive electronics
Signal amplification in vehicle control modules
Low-side driver stages in embedded systems

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging format and reel specifications. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when an automotive-qualified PNP transistor is required in a compact footprint. The SOT363 package suits space-constrained designs. Verify that the 45 V rating and 100 mA current capacity align with circuit demands. Consider the high hFE range for amplifier applications requiring consistent gain characteristics.

Part Context

This part belongs to Nexperia's portfolio of general-purpose bipolar junction transistors. It serves as the PNP complement to NPN variants within the same series. The QX designation indicates automotive qualification, distinguishing it from standard commercial grade parts while sharing similar electrical performance profiles.

Replacement Considerations

Compatible substitutes include BCM857BSH-QX and other AEC-Q101 qualified PNP transistors in the SOT363 package. Verify pinout compatibility and ensure equivalent voltage and current ratings before substitution.
