The BC857CS_R1_00001 is a PNP general-purpose bipolar junction transistor manufactured by Panjit International Inc. It operates with a collector-emitter voltage of 45V and a maximum continuous collector current of 100mA. The device is housed in an SOT-363 surface-mount package, which weighs approximately 8 mg per unit. This component belongs to the DT-02TSP series and is designed for standard switching and amplification applications within electronic circuits.
Verify the specific suffix against official documentation to confirm AEC-Q101 qualification status, as generic part numbers may lack this certification. Confirm the manufacturer's current production status and lead times directly with Panjit or authorized distributors before finalizing procurement plans.
Select this component when automotive-grade reliability is required alongside a compact SOT-363 footprint. Ensure the design accommodates the 100mA current limit and 45V voltage rating. Verify that the PNP polarity matches the circuit topology requirements for the intended application.
This part is a specialized variant within Panjit's BC857 family, distinguished by its automotive qualification. While sharing electrical characteristics with standard commercial versions, the CS suffix indicates adherence to stricter automotive quality standards, differentiating it from non-qualified counterparts like the BC857BS.
Direct replacements must match the SOT-363 package and PNP type. Verify if the alternative component holds AEC-Q101 certification if automotive use is mandatory. Standard BC857 variants may serve as substitutes only if automotive qualification is not required.
