The IXYS MCNA120PD2200TB is a SCR module, featuring a Bipolar Module-Thyristor. It is used for controlling, switching, and regulating the current in AC/DC circuits. The module is configured with two SCRs in a single package, with a 2.2kV maximum reverse blocking voltage. The module has an RMS on-state current of 120A, making it suitable for medium and large power applications. It is designed with a four-pin configuration and a 0.75" by 0.75" size, making it easy to install. The module also features a double pulse triggering mode and a temperature-sense compensation. This makes the module very reliable and capable of withstanding extreme temperature conditions.
