Overview
The IRKT56/14A is a thyristor/diode module from the IRK.56 series, featuring a 1400 V repetitive peak off-state voltage and a 135 A continuous RMS on-state current rating as an AC switch. It utilizes an ADD-A-pak GEN V package with a thick copper baseplate for thermal management. The device supports junction temperatures from -40°C to 125°C and offers high surge capability with an ITSM of 1310 A at 50 Hz.
Feature Summary
- Features a Generation V ADD-A-pak module design combining Direct Bonded Copper substrate with a solid copper baseplate for superior mechanical ruggedness and thermal performance.
- Includes a click-stop feature to secure electrical terminals against axial pull-out, ensuring reliable connection within the module housing.
- Provides 3500 VRMS isolating voltage between the circuit and the grounded heatsink base.
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- UPS systems
Procurement Notes
Verify the specific suffix 'A' denotes Generation V packaging compatibility with TO-240AA standards. Confirm the voltage code '14' corresponds to the required 1400 V rating for the application. Check datasheet revisions for any updates to thermal resistance or mounting torque specifications before finalizing procurement.
Selection Notes
Select this component for general purpose high voltage applications requiring robust surge handling. Ensure the cooling system maintains the case temperature within limits defined by the conduction angle. Verify gate drive parameters do not exceed the maximum peak gate power or voltage ratings specified in the electrical characteristics table.
