IRKH92/10A

Overview

The IRKH92/10A is a Silicon Controlled Rectifier (SCR) module manufactured by Vishay General Semiconductor. It features a single element configuration housed in an ADD-A-PAK package with five terminals. The device supports a repetitive peak reverse voltage of 1000V and a maximum on-state current of 90A. It includes a built-in diode for enhanced functionality. The module utilizes a thick aluminum die and double stick bonding for reliability, along with a thick copper baseplate for thermal management.

Feature Summary

• High voltage industrial standard package design
• Thick aluminum die and double stick bonding construction
• Thick copper baseplate for superior thermal performance
• UL recognized component with isolated case connection

Applications

• Industrial power control systems
• High voltage rectification circuits
• Power supply applications requiring robust SCR modules

Procurement Notes

Verify the specific suffix and revision level against the official Vishay datasheet to ensure compatibility with system requirements. Confirm that the ADD-A-PAK mechanical dimensions match the intended heatsink interface. Check for any lead-free or RoHS compliance status updates if environmental regulations apply to the final assembly. Ensure the gate trigger parameters align with the driving circuit capabilities.

Selection Notes

Select this component when a high-voltage SCR with integrated diode functionality is required in a flange-mountable package. The ADD-A-PAK form factor allows for easy mounting on heatsinks while providing electrical isolation. Consider the 1000V rating and 90A current capacity relative to the load requirements. Verify that the thermal resistance characteristics meet the cooling solution design constraints for continuous operation.

Part Context

This part belongs to the IRK series of thyristor modules from Vishay. These modules are designed for industrial applications requiring high reliability and ruggedness. The ADD-A-PAK generation V combines Direct Bonded Copper substrate technology with mechanical stability. The series offers various voltage and current ratings within the same standardized package footprint.

Replacement Considerations

Consult the official Vishay cross-reference documentation for verified substitute part numbers. Ensure that any replacement maintains the same terminal configuration, voltage ratings, and thermal characteristics. Generic equivalents may not replicate the specific internal bonding or insulation properties.
