- Power supply modules
Procurement Notes
Verify compliance with RoHS directives as the specific part may be leaded. Confirm that the UL E78996 approval status meets your regional regulatory requirements. Ensure the selected variant matches the required 800V rating and 95A current capacity for your specific circuit design before finalizing procurement orders.
Selection Notes
Select this component when high voltage isolation and significant surge handling are required in a compact form factor. The thick aluminum die and double stick bonding offer superior thermal stability compared to standard packages. Consider the 3500V RMS isolation if galvanic separation is critical for system safety and noise immunity.
Part Context
This module belongs to the IRK.71 and .91 series thyristor/diode products from Vishay. These components are designed for heavy-duty industrial applications requiring reliable switching under high stress conditions. The series emphasizes durability through robust internal bonding and baseplate materials.
Replacement Considerations
The IRKT91/08A serves as a verified substitute within the same product family. Both parts share identical voltage ratings and package dimensions. Verify that the current handling specifications of the alternative part meet or exceed the original design requirements.
