Procurement Notes

Verify the component authenticity against official onsemi documentation before integration. Confirm that the SOT-23-3 footprint matches your PCB design constraints. Ensure the 200 V reverse voltage rating meets your circuit's peak inverse voltage requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a compact, high-voltage switching diode is required for space-constrained designs. The 200 V rating provides headroom for higher voltage signals compared to standard low-voltage alternatives. Consider the 50 ns recovery time for applications demanding faster switching speeds than standard rectifiers offer.
