  • Semiconductor device
    Patent number: 11496084
    Abstract: A gate voltage control/gate resistance changing circuit (21) is accommodated in the same package (P1) as a switching element (11), and outputs a driving signal to the switching element (11) to control turning on and off of the switching element (11). When an external signal is input from outside of the package (P1) to a terminal (3c) of the package (P1), a changing unit (221) accommodated in the package (P1) changes the switching speed of the switching element (11) based on the signal.
