IRKH162/16

Overview

The IRKH162/16 is a double low-scattering silicon controlled rectifier (SCR) module manufactured by Vishay General Semiconductor. It features an INT-A-PAK package and is rated for 1600V repetitive peak reverse voltage with a 160A average on-state current. The device supports a non-repetitive surge current of up to 5100A at 60Hz. It operates within a junction temperature range of -40°C to 125°C, ensuring reliable performance in high-power industrial applications requiring robust thyristor protection.

Feature Summary

• Double low-scattering SCR configuration for enhanced thermal management
• High surge current capability supporting demanding load conditions
• Robust INT-A-PAK packaging designed for efficient heat dissipation

Applications

• Industrial motor drives and control systems
• High-power AC power regulation circuits
• Resistive and inductive load switching applications

Procurement Notes

Verify the specific suffix designation to confirm the exact voltage rating variant, as the series includes multiple options. Ensure compatibility with existing heatsinking infrastructure due to the module's power density. Confirm that the gate trigger specifications align with the driving circuit requirements before integration into the final assembly design.

Selection Notes

Select this component when high voltage blocking and significant current handling are required in a compact form factor. The double SCR structure offers superior thermal stability compared to single units. Evaluate the gate trigger voltage limits against available drive signals to ensure reliable turn-on characteristics under varying operating temperatures.

Part Context

This part belongs to Vishay's INT-A-PAK family of thyristor modules, designed for high-current industrial applications. The series provides various voltage ratings to suit different system requirements while maintaining consistent mechanical and thermal interface standards across the product line.

Replacement Considerations

Direct substitutes include the VS-VSKU162/16PBF from the same manufacturer, which shares similar electrical ratings and package dimensions. Cross-reference gate trigger parameters carefully when considering alternative manufacturers' offerings to ensure functional equivalence.
