Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix matches the specific RoHS compliance and tape/reel requirements if applicable. Check for obsolescence status as product lifecycles may change. Ensure thermal interface material compatibility with the Super-247 package geometry for optimal heat transfer performance.

Selection Notes

Select this component when designs require high power density in a compact form factor without sacrificing thermal performance. The Super-247 package allows for space savings compared to larger packages like TO-264 while maintaining robustness. Consider the specific gate resistance and drive voltage requirements to optimize switching losses within the 8-40 kHz operational range for hard switching applications.

Part Context

This device belongs to the IRG4PSC/IRG4PSH series of UltraFast IGBTs from Infineon. It utilizes silicon technology and is part of the Generation 4 product line, which focuses on improving efficiency over previous iterations. The Super-247 package is distinct from standard discrete packages, offering enhanced mechanical and electrical isolation characteristics suitable for demanding industrial environments.

Replacement Considerations

Direct replacements include other Generation 4 IGBTs in the Super-247 package with similar voltage and current ratings, such as the IRG4PSH71UD or variants from the IRG4PH series if pinout and thermal characteristics align. Verify that any substitute maintains the required 1200V rating and comparable switching speeds to ensure circuit stability.
