BC857BW-AQ

Overview

The BC857BW-AQ is a PNP bipolar junction transistor manufactured by Diotec Semiconductor, designed for surface-mount applications. It utilizes an SOT-323 package and operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device features a transition frequency of 100 MHz and a power dissipation capacity of 200 mW. It supports an operating temperature range from -55°C to +150°C and holds AEC-Q101 qualification for automotive reliability standards.

Feature Summary

AEC-Q101 qualified for high-reliability automotive environments
Epitaxial die construction for stable performance
Ultra-small SOT-323 surface-mount footprint

Applications

Automotive electronic control systems
General-purpose switching circuits
Signal amplification in compact devices

Procurement Notes

Verify the specific suffix 'AQ' confirms AEC-Q101 automotive qualification status directly on the manufacturer's official datasheet or component specification sheet. Ensure the ordering part number matches the required package type and electrical ratings for your design. Confirm RoHS compliance details through official documentation before procurement.

Selection Notes

Select this component when an automotive-grade PNP transistor is required within a compact SOT-323 form factor. It serves as a complementary counterpart to NPN variants like the BC817 series. Consider its 100 mA current handling and 45 V voltage rating against circuit demands. Verify thermal management requirements align with the 200 mW power dissipation limit in the final assembly.

Part Context

This component belongs to the BC857 family of small-signal PNP transistors produced by Diotec Semiconductor. The 'W' typically denotes the SOT-323 package variant, while 'AQ' indicates automotive qualification. This series is widely used in consumer and industrial electronics requiring reliable switching and amplification in space-constrained designs.
