Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'E' against the official onsemi datasheet to confirm pinout compatibility and electrical tolerances. Ensure the procurement source provides traceable documentation matching the ON Semiconductor part number. Cross-reference the package type to avoid confusion with similar TO-126 variants that may have different lead configurations.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 120V blocking voltage and 1A current capacity is required. Consider the TO-126 package for board-level assembly where space allows for larger footprints. Evaluate thermal dissipation requirements relative to the application's duty cycle and ambient temperature conditions.
