The MCNA95PD2200TB with SCR Modules BIPOLAR MODULE-THYRISTOR manufactured by IXYS is a thyristor module. It is an advanced electronic device consisting of two isolated gates connected to each other through a common semiconductor body, or witch. In layman's terms, it acts as an electrically operated switch that can be opened or closed to control the flow of electric current through an electric circuit. This module is used for power control applications like static switching, motor control, phase control, soft start, over-voltage protection, and crowbar protection. The MCNA95PD2200TB is rated for a maximum current of 22 A, a maximum voltage of 950 V, and a reverse voltage of 650 V. It is designed to withstand a surge of up to 2 A, and is RoHS compliant.
