Single Bipolar Transistors Procurement Notes

Verify the specific suffix BK against official Diotec documentation to confirm packaging configuration. Ensure the part status remains active before procurement. Cross-reference the manufacturer product number with authorized distributor listings to validate authenticity. Confirm RoHS compliance requirements match project specifications.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required for low-level signal processing. The 30 V rating limits suitability for higher voltage environments compared to BC546 variants. Consider the TO-92 package constraints for thermal management in dense PCB layouts. Verify that the 100 mA current limit aligns with load requirements.

Single Bipolar Transistors Part Context

This transistor belongs to the BC548 series, which includes variants distinguished by gain binning. The BC548C designation indicates the highest gain tier within the standard 30 V family. It serves as a complementary counterpart to PNP devices like the BC558 series. The BK suffix typically denotes bulk or tape-and-reel packaging variations distinct from cut-tape formats.
