Abstract
An electronic component, such as an IGBT, that presents a control terminal for receiving a stepwise control signal and at least one other terminal adapted for reaching a given voltage level by effect of the application of the step signal, with the possibility of overshoot occurring; and a damping resistive element interposed between the control terminal and the at least one other terminal. The damping resistive element shows a current saturated behavior correlated to voltage increase applied at the terminals towards the given voltage level, thus eliminating the risk of occurrence of overshoot in the voltage of the IGBT collector, and preventing the undesired re-ignition of the IGBT when it is in a cut-off condition, by inducing an overvoltage on the collector terminal.
