Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with the required tape-and-reel packaging configuration. Confirm that the TP-FA package variant matches the intended PCB footprint and thermal management requirements. Check for any recent product change notifications or discontinuance notices from onsemi regarding this specific part number before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor with 100 V breakdown voltage and 3 A continuous current capability is required in a compact surface-mount form factor. The low saturation voltage makes it suitable for applications where minimizing power loss during the on-state is critical. Ensure the thermal design accounts for the 1 W power dissipation limit under expected load conditions.
