Procurement Notes

Verify the specific suffix 'H' against official manufacturer documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status distinct from the standard 'T4G' designation. Ensure the component matches the required RoHS and REACH standards for your assembly process. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring fast recovery times to minimize switching losses and electromagnetic interference. The TO-252 package offers a balance between thermal performance and board space efficiency for medium-power applications. Evaluate the 200 V rating against peak transient voltages in the target system to ensure adequate safety margins during operation.
