SEMICONDUCTOR DEVICE

摘要

The connection pattern of a plurality of diodes (D) includes a series connection pattern (11) extending in the X-direction from an input terminal (8), and a series connection pattern (12) including a section through which a current flows so as to approach the input terminal (8) side. Series connection pattern (11) includes the first diode (DF) when counting from the input terminal (8). Series connection pattern (12) includes the last diode (DL) when counting from the input terminal (8). Diode (DL) is positioned at a distance in the Y-direction from diode (DF). Furthermore, the N-type region (NR) of diode (DF) and the P-type region (PR) of diode (DL) directly face one another when seen from a planar view.
