Single Bipolar Transistors Procurement Notes

Verify the specific suffix BK against official Diotec documentation to confirm packaging and binning details. Ensure the procurement channel provides valid traceability for RoHS3 compliance. Cross-reference the manufacturer part number with authorized distributor listings to confirm active status and avoid obsolete stock. Confirm that the received components match the specified TO-92 physical dimensions.

Single Bipolar Transistors Selection Notes

Select this component when a 45 V collector-emitter voltage rating is required, distinguishing it from lower-voltage variants like the BC548 series. The high hFE binning makes it suitable for applications demanding significant current amplification without excessive base drive current. Consider the TO-92 package constraints for thermal management in enclosed designs compared to surface-mount alternatives.

Single Bipolar Transistors Part Context

This component belongs to the BC54x family of NPN transistors produced by Diotec Semiconductor. It shares the same physical footprint and general electrical characteristics as other members of the series, differentiated primarily by their DC current gain sorting bins. The BC547 variant specifically offers a higher voltage rating than the BC548, providing design flexibility for medium-voltage switching tasks.

Single Bipolar Transistors Replacement Considerations

BC547B is a parameter-equivalent alternative within the same product family.
