Schottky diode resisting overcurrent, with low blocking current, is formed with defined, differing spacings between regions of differing conduction type

摘要

To initiate injection of triggering current, at least one region (4, 5) of the other conduction type is so formed that minimum spacing (D) from the center of one region (5) to a region of one conductor type, is greater than the corresponding least spacing (d) to remaining regions (4) of the other conduction type.
