1. A solid state relay, comprising:
a first thyristor and a second thyristor connected in antiparallel between a first relay terminal and a second relay terminal;
wherein an anode of the first thyristor is connected to the first relay terminal; and
a control device comprising:
a triac; and
a first diode series-connected between the triac and a first terminal of the control device, wherein the first terminal is configured to be connected to a cathode gate of the first thyristor; and
wherein a second terminal of the control device is configured to be connected to an anode of the first thyristor and the first relay terminal;
wherein the triac has a gate connected to a third terminal of the control device, wherein the third terminal is configured to receive a control signal.
