Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized channels as this part is officially discontinued and not recommended for new designs. Confirm that the specific ordering suffix matches the required pinout configuration, as variations exist within the family. Ensure compliance with RoHS standards if applicable to your manufacturing process before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component only for legacy maintenance or existing design modifications where the original schematic specifies the KSC945 series. Evaluate thermal resistance and junction temperature limits carefully during circuit layout. Consider the discontinuation status when planning long-term production runs or supply chain stability.

Single Bipolar Transistors Part Context

This device belongs to the KSC945 family of NPN epitaxial transistors produced by onsemi. It utilizes a standard TO-92-3 case outline designed for through-hole mounting. The specific OTA suffix indicates a particular packaging and shipping configuration distinct from other variants like the OBU or CYTA models.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly states the KSC945 is discontinued and recommends contacting onsemi representatives for information. No direct public substitute part numbers are provided in the documentation.
