A FET bidirectional switching arrangement comprises first and second FETs, and a limiting arrangement connected to the FETs. The FETs are operable in response to a first bias condition to pass current in series through the FETs in either of two opposite directions, and operable in response to a second bias condtion to block current through the FETs in both of the two opposite directions. The limiting arrangement senses the direction of current flowing through the FETs and limits a forward bias on a first pn junction of the first FET when the current flows in a first direction of the two opposite directions to limit undesired current flow through the first pn junction of the first FET. When the current flows in a second direction of the two opposite directions, the limiting arrangement limits a forward bias on a first pn junction of the second FET to limit undesired current flow through the first pn junction of the second FET.
