Single Bipolar Transistors Procurement Notes

Verify the exact datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the TO-220AB package matches your thermal management requirements. Ensure the component meets all electrical specifications for your specific voltage and current loads.

Single Bipolar Transistors Selection Notes

Select this component when a 400 V rating and 10 A continuous current are required in a standard through-hole package. The integrated resistor reduces external component count compared to bare transistors. Evaluate thermal resistance characteristics against your heatsinking strategy to ensure safe operating area compliance during switching transitions.

Single Bipolar Transistors Part Context

This part belongs to onsemi's lineup of discrete power transistors. It serves as a fundamental building block for medium-power AC/DC conversion stages. The TO-220AB form factor provides a balance between current handling capacity and ease of manual assembly or automated placement in industrial equipment.

Single Bipolar Transistors Replacement Considerations

Consult official substitution guides for equivalent NPN power transistors with matching voltage and current ratings. Verify pinout compatibility and thermal performance metrics before replacing the original component in existing designs.
