IRKT92/12A

Overview

The IRKT92/12A is a dual silicon controlled rectifier (SCR) module manufactured by Vishay General Semiconductor. It features a repetitive peak off-state voltage of 1.2 kV and a continuous on-state current of 210 A RMS, with an average current rating of 95 A. The device utilizes a Series connection topology and is housed in an ADD-A-PAK (3 + 4) chassis mount package. This component is designed for high-power industrial applications requiring robust thyristor control.

Feature Summary

• Dual SCR configuration within a single integrated module
• High voltage blocking capability up to 1.2 kV
• Chassis mount design for efficient thermal management
• Series connection topology for flexible circuit integration

Applications

• Industrial motor drives and control systems
• High-power DC power supply circuits
• Resistive load control applications
• Welding equipment power stages

Procurement Notes

Verify the specific datasheet version to confirm gate trigger current parameters and thermal resistance values. Ensure that the procurement documentation explicitly lists the ADD-A-PAK mounting interface dimensions. Confirm compliance with RoHS standards if required by the final assembly specifications. Cross-reference the part number suffix to ensure no functional variations exist between manufacturing batches.

Selection Notes

Select this module when a dual SCR solution is required for high-current AC or DC switching. The 1.2 kV rating suits medium-voltage industrial networks. Consider the 210 A RMS capacity against the actual load requirements. The chassis mount form factor necessitates compatible heatsinking infrastructure. Evaluate the gate drive requirements against available control circuitry capabilities.
