• Small signal amplification stages
• Power supply control logic

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as this component originates from Sanyo Electric Co Ltd and is now distributed by onsemi. Confirm that the specific suffix matches the required package and tape-and-reel specifications. Ensure the source documentation explicitly lists the part number to avoid confusion with similar high-voltage PNP transistors in the portfolio.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 400V collector-emitter rating is required. The 200mA current limit and 70MHz transition frequency define its suitability for moderate-speed switching tasks. Consider the 150°C junction temperature rating for thermal management planning in enclosed environments.

Single Bipolar Transistors Part Context

This transistor belongs to the family of small signal bipolar devices originally developed by Sanyo Electric. Following corporate restructuring, these products are managed under the onsemi brand. The part represents a standard discrete solution for high-voltage PNP applications where specific Sanyo legacy specifications are mandated by existing designs.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the 400V VCEO, 200mA Ic, and PNP configuration. Verify pinout compatibility and package dimensions before swapping. Cross-reference datasheets to ensure equivalent transition frequencies and thermal characteristics.
