IRKH105/14A

Overview

The IRKH105/14A is a high-power Silicon Controlled Rectifier (SCR) module manufactured by Vishay General Semiconductor. It features a series connection configuration of SCR and diode elements housed in an ADD-A-PAK package. The device is rated for a maximum repetitive peak off-state voltage of 1400 V and a non-repetitive surge current of 1785 A at 50 Hz or 1870 A at 60 Hz. Key electrical specifications include a maximum gate trigger voltage of 2.5 V and a maximum gate trigger current of 150 mA.

Feature Summary

Series-connected SCR and diode structure for robust power handling
High surge current capability suitable for demanding industrial loads
Designed for high-voltage applications with reliable switching characteristics

Applications

Industrial motor drives and control systems
High-power DC to AC inverters
Resistive load control applications

Procurement Notes

Verify the specific suffix '14A' corresponds to the 1400V rating, as other variants like '04A' exist with different voltage ratings. Confirm the ADD-A-PAK mounting interface requirements for thermal management. Ensure gate drive circuits comply with the specified 2.5V max trigger voltage and 150mA max trigger current limits to prevent device damage during operation.

Selection Notes

Select this component when high voltage blocking capability and significant surge current tolerance are required in a single module. The series SCR-diode topology offers protection against reverse voltage while managing high forward currents. Consider the thermal resistance of the ADD-A-PAK package for heat sink design. Compare against IRKT105/14A if alternative packaging or slight parameter variations are acceptable for the specific application constraints.

Part Context

This part belongs to the IRKH series of thyristor modules from Vishay. These modules are engineered for heavy-duty power electronics. The IRKH105/14A specifically addresses applications requiring 1400V isolation and high current switching. It complements lower voltage variants within the same product family, providing a scalable solution for medium to high-power industrial converters.
