Bi-directional switch

摘要

A bi-directional switch that includes a first terminal, a second terminal, and a plurality of ballast circuits is provided. Each ballast circuit includes a first metal-oxide-semiconductor field-effect transistor (MOSFET) comprising a first input connector, a first output connector, a first body, and a first body diode, and a second MOSFET comprising a second input connector, a second output connector, a second body, and a second body diode. Each first input connector is coupled to the first terminal, each second input connector is coupled to the second terminal, and each first output connector is coupled only to the second output connector of the second MOSFET that is in a same ballast circuit.
