Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact binning or packaging variations. Confirm RoHS compliance status as indicated in the latest datasheet revision. Check for end-of-life notices or product change notifications prior to final design approval. Ensure the sourcing channel provides valid traceability for the Diodes Incorporated manufacturing origin.

Selection Notes

Select this component when a low-cost, single Schottky diode with 20 V blocking capability is required. The 500 mA current rating suits moderate power applications where space constraints favor the SOD-123-2 footprint. Consider the 385 mV forward voltage for efficiency calculations in low-voltage DC systems. Evaluate thermal management requirements based on the 410 mW power dissipation limit.
