A circuit can comprise a transistor, a sensor, and a switch. The transistor can include a drain electrode, a gate electrode, a source electrode, and a back electrode. The sensor can be configured to detect an error condition in the transistor. The switch can be configured to change a voltage at the back electrode in response to the sensor detecting the error condition in the transistor, the change of the voltage at the back electrode reducing current flow between the drain electrode and the source electrode.
