Overview
The IRKT41/10A is a thyristor/diode module from the ADD-A-pak GEN V series, rated for 1000 V repetitive peak off-state voltage and 45 A average on-state current. It features a TO-240AA case style with an isolated baseplate. The device includes a built-in diode and offers high surge capability with an ITSM of 850 A at 50 Hz. Operating junction temperature ranges from -40 to 125 °C.
Feature Summary
- High voltage industrial standard package
- Thick copper baseplate for improved thermal spread
- Direct Bonded Copper substrate for excellent thermal performance
- Mechanical ruggedness without hard mold stress
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- UPS and battery chargers
Procurement Notes
Verify the specific voltage code suffix (e.g., /10A indicates 1000V) against the official ordering table to ensure correct blocking voltage ratings. Confirm that the required dv/dt rating matches the standard 500 V/µs specification unless the S90 variant is explicitly needed. Check lead times as these are specialized industrial modules.
Selection Notes
Select based on the required RMS isolation voltage of 3500 VRMS and the maximum internal thermal resistance of 0.23 K/W. Ensure the mounting torque meets the specified 5 Nm requirement for the busbar connection. Consider the conduction angle derating curves when calculating average current limits for non-sinusoidal loads.
Part Context
This component belongs to the IRK.41/.56 series of ADD-A-pak GEN V power modules. These modules combine Direct Bonded Copper substrates with solid copper baseplates for superior mechanical ruggedness and thermal performance. The series is designed for general-purpose high-voltage applications requiring reliable switching in industrial environments.

FAQ
What is the maximum critical rate of rise of off-state voltage?
The maximum critical rate of rise of off-state voltage (dv/dt) is 500 V/µs at a junction temperature of 125°C with the gate open circuit.
Does this module include an auxiliary cathode?
Yes, the IRKT41/10A configuration includes an auxiliary cathode. Types without an auxiliary cathode use different part numbers such as IRKT42.
What is the UL approval number for this module?
The module is UL approved under file number E78996.
