Abstract: A driving circuit is provided for a control terminal of a bipolar transistor in an emitter-switching configuration. The emitter-switching configuration is between first and second voltage references. The driving circuit includes at least one first resistive element connected to the control terminal of the bipolar transistor and a first capacitor connected to the resistive element with respect to a first circuit node and to the second voltage reference. The driving circuit further includes a Zener diode connected between the first circuit node and a second circuit node, and a second capacitor between the second circuit node and the second voltage reference.
