Disclosed is a semiconductor apparatus having an IGBT, which includes a switch SWon 1 for supplying a gate current during an operation for turning on the gate of the IGBT, a switch SWoff 1 for discharging a gate capacitance during an operation for turning off the gate, a switch SWon 2 for increasing the gate current, a timer 14 for turning on the switch SWon 2 in conjunction with the turn-on of the switch SWon 1 and then maintaining the turn-on of the switch SWon 2 only for a first predetermined time, a switch SWoff 2 for increasing the discharge current during the gate turn-off operation, and a timer 15 for turning on the switch SWoff 2 in conjunction with the turn-on of the switch SWoff 1 and then maintaining the turn-on of the switch SWoff 2 only for a second predetermined time.
