Overview
The BC857CW-TP is a PNP silicon bipolar junction transistor manufactured by Micro Commercial Components. It is housed in an SOT-323 surface-mount package and certified to AEC-Q101 automotive standards. The device supports a maximum collector current of 100 mA with a collector-emitter voltage rating of 45 V and a collector-base voltage of 50 V. It features a low saturation voltage of 650 mV at 5 mA base and 100 mA collector currents, ensuring efficient switching performance. The component operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q101 standard for high-stress environments.
- Optimized for low-voltage drop applications through minimized collector-emitter saturation characteristics.
- Designed for compact circuit layouts utilizing the ultra-small SOT-323 surface-mount footprint.
Applications
- Automotive electronic systems requiring qualified discrete components
- General-purpose signal amplification circuits
- Electronic switching applications
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm AEC-Q101 qualification status, as generic designations may vary. Ensure the ordering information matches the exact electrical ratings required for the target application. Cross-reference datasheet revisions to confirm compliance with current environmental directives such as RoHS. Confirm package dimensions align with PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when automotive reliability standards are mandatory for the design. The SOT-323 package is suitable for space-constrained boards where single-transistor functionality is sufficient. Consider the 100 mA current limit and 45 V voltage rating to ensure operation remains within safe limits. Verify thermal management requirements given the 150 mW power dissipation capability in the specified package.
Part Context
This part belongs to the BC857 series of PNP transistors produced by Micro Commercial Components. It serves as the complementary counterpart to NPN devices like the BC847 series. The CW variant specifically denotes the SOT-323 package configuration. This family is widely utilized in consumer electronics and industrial control systems requiring small-signal processing capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference lists or authorized distributor databases for verified equivalents. Ensure any replacement maintains identical pinout configurations and meets the same AEC-Q101 automotive qualification requirements.
