Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'S' against official onsemi documentation to confirm packaging details, as standard listings may reference bulk or tape-and-reel variations. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm the accuracy of the thermal resistance and pinout information provided in the manufacturer's latest release.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage, high-current PNP switch is required in a compact through-hole form factor. The 20V rating suits low-side or high-side control in 12V systems. Consider the 1W power dissipation limit and ensure adequate heatsinking or PCB copper area is allocated to maintain junction temperatures within safe operating limits during continuous operation.

Single Bipolar Transistors Part Context

This part belongs to onsemi's general-purpose discrete transistor portfolio. It serves as a robust alternative for legacy designs requiring reliable PNP switching in consumer electronics and industrial control boards. The TO-92VAR package offers space efficiency compared to larger power packages while maintaining sufficient current handling for moderate load applications.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the 20V V(BR)CEO, 5A IC, and TO-92VAR package constraints. Verify pinout compatibility (Emitter-Base-Collector vs. Base-Collector-Emitter) before substitution. Generic replacements should be sourced from qualified manufacturers with identical absolute maximum ratings to ensure circuit reliability.
