Light-activated thyristor for e.g. switching of load, has ignition stage including conductor structure with conductor segments, which are distanced from each other and electrically contact n-doped ignition stage emitter and P-doped base

摘要

The thyristor (100) has a p-doped emitter (8), an n-doped base (7), a P-doped base (6) and an n-doped main emitter (5) arranged in a vertical direction (v) in a semiconductor body (1). An ignition stage structure is arranged between an ignition device (BOD) and the main emitter and comprises an ignition stage (AG3) with an n-doped ignition stage emitter (53). The ignition stage has a conductor structure (43) with conductor segments (M3), which are distanced from each other. The conductor segments electrically contact the n-doped ignition stage emitter and the P-doped base. An independent claim is also included for a switch arrangement including a control connecting device.
