Procurement Notes

Verify the specific datasheet version and official documentation from Vishay before implementation, as component specifications may be subject to change. Confirm that the MTK package dimensions align with your PCB footprint requirements. Ensure that thermal management solutions are adequate for the 110 A current rating under your specific operating conditions. Check for any recent obsolescence notices or replacement recommendations directly from the manufacturer.

Selection Notes

Select this component when a three-phase rectification topology is required with high current capacity. The 800 V reverse voltage rating suits medium-voltage industrial applications. Consider the MTK package constraints for thermal dissipation and mechanical mounting. Evaluate the forward voltage characteristics against system efficiency targets. Compare against alternative packages if space or thermal constraints differ significantly from the MTK form factor.
