A bipolar junction transistor (BJT) used as a synchronous rectifier (SR) that is turned off by an active electronic device such as a transistor coupled between the base and collector of that SR BJT. The turn-off transistor functions to rapidly remove stored charge from the collector-base junction of the SR BJT when appropriate. Various active electronic devices are discussed as implementations of the turn-off transistor, including bipolar and field effect transistors of same or opposite polarity. Various anti-saturation and base current increasing circuits are also disclosed.
