Overview
The IRKU105/08A is a thyristor/thyristor module from the IRK.U/V105 series, manufactured by Vishay General Semiconductor - Diodes Division. It features an ADD-A-pak Gen V package with a TO-240AA case style. The device supports a maximum average on-state current of 105 A at 85°C and an RMS current of 165 A. It offers a repetitive peak off-state voltage range of 400 to 1600 V, with the /08A code specifying 800 V. Key electrical ratings include a non-repetitive surge current of 1785 A at 50 Hz and 1870 A at 60 Hz. The junction temperature range is -40 to 130°C.
Feature Summary
- Utilizes Direct Bonded Copper (DBC) substrate for superior thermal performance and mechanical ruggedness.
- Features a thick copper baseplate that facilitates easier mounting on heatsinks and improves thermal spreading.
- Includes a solid copper baseplate at the bottom side of the device for increased tolerance of surface roughness.
- Electrical terminals are secured against axial pull-out using a reliable click-stop feature.
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- UPS systems
Procurement Notes
Verify the specific voltage code suffix to confirm the exact blocking voltage rating, as the IRKU/V105 series spans multiple voltage levels. Confirm the generation designation 'A' corresponds to the Gen V package specifications. Ensure compatibility with the required dv/dt rating if operating in high-speed switching environments, as standard versions differ from S90 variants.
Selection Notes
Select this module based on the required average on-state current of 105 A and the specific voltage blocking capability needed for the application. Consider the thermal resistance characteristics and the need for heatsink mounting due to the TO-240AA form factor. Evaluate the surge current requirements against the specified ITSM values for both 50 Hz and 60 Hz operation.
Part Context
This component belongs to the IRK.U/V105 series of thyristor modules. It is part of the Generation V Add-A-pak family, which combines DBC technology with a robust copper baseplate. The series is designed for industrial-level applications requiring high voltage and current handling capabilities in a standardized package format.
