Overview
The IRKT57/16A is a thyristor/thyristor module from the IRK.56 series, housed in an ADD-A-pak GEN V package compatible with TO-240AA standards. It features a maximum average on-state current of 60 A and supports voltage ratings up to 1600 V. The device utilizes Direct Bonded Copper substrates for thermal management and includes a solid copper baseplate for mechanical ruggedness. Key electrical characteristics include a peak non-repetitive surge current of 1310 A at 50 Hz and a maximum junction temperature range of -40°C to 125°C.
Feature Summary
- Features high surge capability and industrial standard packaging.
- Utilizes thick aluminum oxide DBC insulator and thick copper baseplate.
- Includes click-stop terminal fixation to secure electrical connections against axial pull-out.
- Offers UL approval and 3500V RMS isolating voltage.
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- UPS systems
Procurement Notes
Verify the specific ordering suffix 'S90' if a critical rate of rise of off-state voltage (dv/dt) of 1000 V/µs is required; otherwise, the standard configuration provides 500 V/µs. Confirm that the module corresponds to the IRK.57 circuit configuration, which indicates the absence of an auxiliary cathode compared to the standard IRK.56 series. Ensure compatibility with TO-240AA mounting hardware.
Selection Notes
Select this component for general-purpose high voltage applications requiring robust thermal performance and mechanical stability. The ADD-A-pak GEN V design facilitates easier mounting on heatsinks with increased tolerance for surface roughness. Consider the 60 A current rating and 1600 V blocking voltage when designing circuits for industrial environments.
Part Context
This module belongs to the IRK.41 and IRK.56 series of thyristor/diode and thyristor/thyristor power modules. The Generation V Add-A-pak technology combines excellent thermal performance with superior mechanical ruggedness. The series is designed for industrial level qualification and offers various voltage codes ranging from 400 V to 1600 V.

FAQ
What is the difference between the IRKT57 and IRKT56 configurations?
The IRKT57 configuration indicates the absence of an auxiliary cathode, whereas the standard IRKT56 includes one.
How does the S90 suffix affect the device specifications?
The S90 suffix specifies a critical rate of rise of off-state voltage (dv/dt) of 1000 V/µs, compared to the standard 500 V/µs.
What is the maximum continuous RMS on-state current for this module?
As an AC switch, the maximum continuous RMS on-state current is 135 A.
