Procurement Notes
Verify the specific suffix '13P' against official MCC documentation to confirm packaging configuration and compliance status. Ensure the component matches the required SOT-23 footprint and electrical ratings for the target design. Cross-reference datasheet parameters such as hFE binning and thermal characteristics before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring a compact PNP transistor with moderate current handling capabilities. The SOT-23 package suits space-constrained printed circuit boards. Verify that the 45V collector-emitter voltage meets the circuit's peak operating requirements and that the 100mA continuous current rating aligns with load demands.
Part Context
This part belongs to the BC857 series of general-purpose PNP transistors produced by Micro Commercial Components. The series is widely utilized in low-power electronic applications due to its reliable performance and standardized surface-mount packaging. The BC857B variant specifically denotes a particular DC current gain classification within the product line.
Replacement Considerations
Compatible substitutes include the BC857BMB from Nexperia or NXP, which share similar electrical characteristics and pin configurations. Other equivalents may include parts from manufacturers like Diodes Incorporated or ON Semiconductor, provided they match the SOT-23 package and PNP polarity.
