Abstract
A solid-state relay is provided, which includes a first transistor, a second transistor, a first transmission circuit, and a second transmission circuit. A gate of the first transistor is connected to one of a source and a drain of the second transistor, one of a source and a drain of the first transistor is connected to a first terminal, and the other of the source and the drain of the first transistor is connected to a second terminal. The first transmission circuit supplies a first signal to the gate of the first transistor. The second transmission circuit supplies a second signal to a gate of the second transistor. The first terminal is connected to the second terminal when the first transistor is turned on by the first signal.
