Abstract

See full text

A semiconductor device of the present invention includes a semiconductor layer including a main IGBT cell and a sense IGBT cell connected in parallel to each other, a first resistance portion having a first resistance value formed using a gate wiring portion of the sense IGBT cell and a second resistance portion having a second resistance value higher than the first resistance value, a gate wiring electrically connected through mutually different channels to the first resistance portion and the second resistance portion, a first diode provided between the gate wiring and the first resistance portion, a second diode provided between the gate wiring and the second resistance portion in a manner oriented reversely to the first diode, an emitter electrode disposed on the semiconductor layer, electrically connected to an emitter of the main IGBT cell, and a sense emitter electrode disposed on the semiconductor layer, electrically connected to an emitter of the sense IGBT cell.
