Bidirectional Shockley diode

摘要

A bidirectional Shockley diode includes an N-type layer sandwiched between two P-type layers. A first N-type region in the P-type region extends over substantially one half of the upper surface. A second N-type region extends in the P-type layer substantially over one complementary half of the surface of the lower surface. Each first and second region protrudes with respect to the median plane of the component by a length r such that ratio r/e is smaller than 0.5, e being the thickness of the component.
