Procurement Notes

Verify the specific suffix (e.g., 16, 10) as it denotes voltage gain grouping. Confirm RoHS compliance status via the official datasheet. Ensure the ordering code matches the required tape-and-reel quantity. Check for any recent PCN updates regarding packaging or labeling changes before finalizing procurement.

Selection Notes

Select this component for high-current PNP switching needs in space-constrained designs. The SOT-223 package offers superior thermal handling compared to smaller SMD packages. Verify that the -80V rating aligns with the system's maximum operating voltage. Consider the hFE binning if precise gain control is critical for the application circuit.
