Patent number: 10916541Abstract: Between a source electrode (25) of a main device (24) and a current sensing electrode (22) of a current detection device (21), a resistor for detecting current is connected. Dielectric withstand voltage of gate insulator (36) is larger than a product of the resistor and maximal current flowing through the current detection device (21) with reverse bias. A diffusion length of a p-body region (32) of the main device (24) is shorter than that of a p-body (31) of the current detection device (21). A curvature radius at an end portion of the p-body region (32) of the main device (24) is smaller than that of the p-body (31) of the current detection device (21). As a result, at the inverse bias, electric field at the end portion of the p-body region (32) of the main device (24) becomes stronger than that of the p-body region (31) of the current detection device (21). Consequently, avalanche breakdown tends to occur earlier in the main device 24 than the current detection device (21).Type: GrantFiled: September 2, 2016Date of Patent: February 9, 2021Assignees: FUJI ELECTRIC CO., LTD., DENSO CORPORATIONInventors: Seiji Momota, Hitoshi Abe, Takashi Shiigi, Takeshi Fujii, Koh Yoshikawa, Tetsutaro Imagawa, Masaki Koyama, Makoto Asai
