Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status and delivery mode. Confirm that the E3 suffix indicates RoHS compliance and commercial grade classification. Ensure the selected packaging matches the required base quantity and delivery format specified in the manufacturer's ordering information section.

Selection Notes

Select this component when an 800 V reverse voltage rating is required for high-efficiency fast switching applications. Verify that the operating junction temperature range of -65 to +175 °C aligns with the thermal environment. Ensure the circuit design accommodates the 1.0 A average forward current limit and the 25 A peak surge capability under transient conditions.
