Overview
The BC857C-AQ is a surface-mount PNP general-purpose transistor manufactured by Diotec Semiconductor in the SOT-23 (TO-236) package. It features a collector-emitter voltage of -45 V, a maximum DC collector current of -100 mA, and power dissipation of 250 mW. The device meets AEC-Q101 qualification standards for automotive applications. It offers three current gain groups with Group C providing a minimum hFE of 270 at IC = 10 µA and 420 at IC = 2 mA. Operating junction temperature ranges from -55°C to +150°C.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- Three selectable DC current gain groups for precise amplification control
- RoHS compliant and free of conflict minerals
Applications
- Signal processing circuits
- General purpose switching applications
- Amplification stages
Procurement Notes
Verify that the specific ordering suffix matches the required grade. Confirm the presence of the -AQ designation indicates AEC-Q101 qualification rather than standard commercial or industrial grades. Ensure the component is sourced directly from authorized channels to guarantee authenticity and traceability for automotive-grade specifications.
Selection Notes
Select this component when an automotive-qualified PNP transistor is required for low-current signal handling. The BC857C variant provides higher current gain compared to Groups A and B. Verify that the -45 V rating and -100 mA current limits align with the target circuit design constraints before integration.
Part Context
This part belongs to the BC856...BC860 series of SMD universal PNP transistors. It serves as the complement to NPN transistors such as the BC847. The -AQ suffix specifically denotes AEC-Q101 qualification, distinguishing it from the standard commercial (-C) or industrial grade versions within the same product family.
