IRKH26/06A

Overview

The IRKH26/06A is a thyristor/diode module manufactured by Vishay General Semiconductor - Diodes Division. It features a 600V repetitive peak reverse voltage and an average on-state current of 27A, with an RMS rating of 60A. The device utilizes the ADD-A-PAK package, providing a flange mount configuration with five pins. It includes a built-in diode in series connection with the SCR. Key electrical parameters include a maximum gate trigger voltage of 2.5V and a non-repetitive surge current of 400A at 50Hz or 420A at 60Hz. The junction temperature range extends from -40°C to 125°C.

Feature Summary

• Integrated series connection of Silicon Controlled Rectifier and diode within a single module
• High surge current capability designed for demanding industrial power applications
• Thick copper baseplate construction utilizing Direct Bonded Copper substrate for superior thermal performance
• Isolated case connection with UL recognition for enhanced safety and grounding flexibility

Applications

• Industrial motor drives and control systems
• High voltage power conversion circuits
• Resistive heating and welding equipment
• Static switch applications requiring high isolation voltage

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact electrical ratings and package compatibility. Ensure that the procurement channel provides valid traceability for AEC-Q101 or relevant industrial certifications if required by the application. Confirm that the ADD-A-PAK mounting interface matches the mechanical design constraints of the target heatsink assembly prior to ordering.

Selection Notes

Select this component when a combined SCR and diode solution is required in a compact, thermally efficient package. The 600V rating suits medium-voltage industrial environments where high surge tolerance is critical. Consider the 27A average current limit and the need for adequate heatsinking due to the TO-240AA compatible form factor. Evaluate the isolated flange mount option for applications necessitating grounded heatsinks without electrical shorting.

Part Context

The IRKH26/06A belongs to the IRKH26 series of thyristor modules produced by Vishay General Semiconductor. This series is characterized by the use of Generation V Add-A-Pak technology, which combines robust mechanical packaging with advanced thermal management via aluminum oxide DBC insulators. The family offers various voltage ratings, with the 06A variant specifically designated for 600V operations, maintaining consistency in current ratings and physical dimensions across the series.

Replacement Considerations

Cross-reference with other Vishay IRKH26 series variants such as IRKH26/08A or IRKH26/12A for higher voltage requirements. Verify mechanical pinout compatibility with existing PCB or chassis layouts. Ensure that alternative sources maintain the same lead-free status and RoHS compliance standards as specified in the original datasheet.
