Single Bipolar Transistors Procurement Notes

Verify the specific suffix BBK against official Diotec documentation to confirm package type and tape/reel specifications. Ensure the requested quantity aligns with manufacturer standard packaging configurations. Confirm RoHS compliance status directly from the latest datasheet before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 65V breakdown voltage and 100mA continuous current capacity is required. Consider the TO-92BK through-hole package for manual assembly or standard PCB mounting. Evaluate the hFE range requirements against application needs, noting the maximum gain specification provided in the datasheet.

Single Bipolar Transistors Part Context

This part belongs to the BC556 series of PNP silicon epitaxial planar transistors. The series is subdivided into groups based on current gain characteristics. The BC556 variant specifically offers higher voltage ratings compared to lower-voltage counterparts like the BC558, making it suitable for applications requiring greater collector-emitter voltage headroom.

Single Bipolar Transistors Replacement Considerations

BC557BBK: Offers similar current and power ratings but with a reduced collector-emitter voltage of 45V. Verify voltage requirements before substitution.
