Many readers may not know MOS-SCR yet. It is a SCR in which the input is equivalent to the gate of a MOS field effect transistor, that is, it has a high impedance. The other features, such as trigger voltage and maximum controlled current, are the same as the MCR106 or TICl06, for Motorola MCR1000-4. In fact, the -4 indicates that the maximum voltage between cathode and anode for this SCR in the non-conduction condition is 200 V. In the figure we have a way to use this SCR in a full wave control for the power grid from the output of a CMOS logic circuit, such as a 4001 gate. Of course, depending on the current controlled, the SCR needs to be mounted on a heat radiator. Likewise, the diodes that form the bridge for full wave conduction must be able to handle the voltage and current of the load.
