PURPOSE: A semiconductor apparatus is provided to prevent a power device from malfunction even when a dv/dt transient signal is supplied with time difference. CONSTITUTION: A semiconductor apparatus is provided with a level shift circuit(100), a half bridge type power device made of power devices(12,13) connected with each other, installed between the positive and negative pole of a power supply(PS), wherein the power device is made of an insulating gate type bipolar transistor, a plurality of diodes(D1,D2) connected to the power devices with reverse-parallel, respectively, and a load part, such as a motor, connected to a connection point(N1) generated between the power devices.
