Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and shipping quantity. Confirm compliance requirements such as RoHS status directly from the manufacturer's datasheet before procurement. Ensure thermal management aligns with the specified junction-to-case thermal resistance values during integration.

Selection Notes

Select this component for high-frequency power conversion designs requiring fast recovery times. Evaluate the 200 V reverse voltage rating against circuit peak voltages. Consider the TO-247-3LD package for through-hole mounting and adequate heat dissipation. Verify that the 15 A average current rating meets the continuous load requirements of the application.
