According to an exemplary implementation, a switching circuit includes a bipolar junction transistor, a base current supply configured to turn-on the bipolar junction transistor, and a base discharge switch configured to selectively draw current away from a base of the bipolar junction transistor so as to turn-off the bipolar junction transistor. The base discharge switch can further be configured to selectively prevent the base current supply from providing current to the base of the bipolar junction transistor. The base discharge switch may be coupled across the base of the bipolar junction transistor and an emitter of the bipolar junction transistor. The base discharge switch can further be configured to selectively cause the base of the bipolar junction transistor to have a base voltage substantially lower than an emitter voltage of the bipolar junction transistor. |
