The BC857CS-AU_R1_000A1 is a PNP general-purpose transistor manufactured by Panjit International Inc. It is housed in an SOT-363 surface-mount package and carries AEC-Q101 automotive qualification. The device supports a collector-emitter voltage (VCEO) of 45 V, a collector-base voltage (VCBO) of 50 V, and an emitter-base voltage (VEBO) of 5 V. Continuous collector current is rated at 100 mA with a maximum power dissipation of 225 mW. Operating junction and storage temperatures range from -55°C to +150°C. Electrical characteristics include a DC current gain (hFE) ranging from 100 to 300 at IC = -10 mA and VCE = -5 V.
Verify component authenticity by cross-referencing the manufacturer's datasheet specifications against the received hardware markings. Confirm that the marking code matches '57C' as documented in the official Panjit datasheet. Ensure compliance with environmental requirements such as lead-free status and halogen-free composition prior to integration into final assemblies.
Select this component when a PNP transistor with a 45 V collector-emitter rating and 100 mA continuous current capacity is required. The SOT-363 package provides a space-efficient solution for surface-mount designs. Verify that the thermal resistance and power dissipation limits align with the specific circuit's operating conditions and ambient temperature constraints.
This part belongs to the BC857CS-AU series of PNP general-purpose transistors produced by Panjit International Inc. The suffix '_R1_000A1' indicates a Tape and Reel packaging configuration on a 7-inch reel with RoHS compliance. The series is designed for high-volume manufacturing and meets TS16949 quality system certification standards.
