Procurement Notes

Verify the specific voltage rating suffix (e.g., 400V vs 600V) against the required circuit specifications before procurement. Confirm that the 'R' designation indicates reversed leads as documented in the datasheet. Ensure compatibility with the specified thermal resistance values for heat sink selection. Validate that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component for applications requiring robust surge handling and fast switching speeds. The three-tower package facilitates efficient mounting and cooling. Consider the 90 ns reverse recovery time when designing snubber circuits or assessing EMI performance. Ensure the average forward current rating aligns with the continuous load requirements while accounting for derating at elevated temperatures.
