Overview
The IRKT106/12A is a thyristor/diode module from the IRK.105 series, rated for 1200 V repetitive peak off-state voltage and 105 A average on-state current at 85°C case temperature. It features a TO-240AA (ADD-A-PAK) package with an isolated baseplate and supports junction temperatures up to 130°C. The device includes a built-in diode with a maximum RMS current of 235 A when used as an AC switch.
Feature Summary
- Features a thick copper baseplate and Direct Bonded Copper substrate for superior thermal performance and mechanical ruggedness.
- Includes a click-stop feature to secure electrical terminals against axial pull-out.
- Provides high surge capability with non-repetitive peak currents reaching 1785 A at 50 Hz.
- Offers industrial standard isolation with a 3500 Vrms isolating voltage rating.
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- Uninterruptible Power Supply (UPS) systems
Procurement Notes
Verify the specific voltage code suffix matches the required blocking voltage, as the IRK.105 series spans 400V to 1600V. Confirm the dv/dt rating requirements; standard units are rated at 500 V/µs, while higher ratings require a specific S90 suffix. Ensure mounting hardware complies with the specified torque values for reliable thermal contact.
Selection Notes
Select based on the required repetitive peak off-state voltage and average on-state current derating curves relative to case temperature. Consider the thermal resistance characteristics and conduction angles for power loss calculations. Verify gate triggering parameters against the driver circuit capabilities, particularly at varying junction temperatures.
Part Context
This component belongs to the IRK.105 series of Generation V ADD-A-PAK modules manufactured by International Rectifier (Infineon). The series utilizes thick aluminum metal die bonding and double-stick bonding techniques. It is designed for general-purpose high-voltage industrial applications requiring robust mechanical and thermal performance.
Replacement Considerations
IRKT106/14A: Higher voltage rating (1400 V) within the same series. IRKT106/16A: Highest voltage rating (1600 V) in the standard configuration. IRKT106/12AS90: Same voltage but enhanced dv/dt rating of 1000 V/µs.
FAQ
What is the difference between the IRKT106/12A and IRKT106/12AS90?
The IRKT106/12AS90 has an enhanced critical rate of rise of off-state voltage (dv/dt) rating of 1000 V/µs, whereas the standard IRKT106/12A is rated at 500 V/µs.
How does the IRKT106/12A differ from the IRK.105 series?
The IRKT106/12A is part of the IRK.106 sub-series, which indicates it has no auxiliary cathode, unlike some configurations in the broader IRK.105 family that may include auxiliary terminals.
What is the maximum junction temperature for this module?
The maximum operating junction temperature range is -40°C to 130°C.
