Title:
POWER SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100377
Kind Code:
A1
Abstract:
The present invention improves the current detection precision of a power semiconductor device. A power semiconductor device according to the present invention comprises: an insulating substrate on one side of which is disposed a first conductor layer; a semiconductor element; a main terminal connected to the first conductor layer; and a current-detecting element. The current-detecting element comprises a front electrode connected to the semiconductor element, via a conductor member, on one side thereof, and a rear electrode connected to the first conductor layer on the other side thereof. Defining the side, of the current-detecting element, closest to the main terminal as a first side and a side at a position facing the first side as a second side, a connection between a detector terminal and the rear electrode is provided on the side closer to the second side.
