摘要： The present invention provides a switching circuit and an electronic switching component having a switching semiconductor device to perform switching between a conducting state and a non-conducting state of a conducting path to thereby reduce the power loss thereof and a control method thereof. In the present invention, at least two FETs 11 and 12, wherein the FET 11 has a faster switching time and the FET 12 has a lower ON resistance. Active terminals (drains and sources) of the FETs 11 and 12 are connected to each other in parallel. By employing these FETs 11 and 12, the conversion between an ON-state and an OFF-state of the conducting path is performed. In converting from the non-conducting state to the conducting state, the control circuit 13 first turns on the FET 11 and then turns on the FET 12 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof. In converting from the conducting state to the non-conducting state, the control circuit 13 first turns off the FET 12 and then turns off the FET 11 when if a voltage between terminals of the FET 11 reaches around a saturation value thereof.
