Static induction emitter diode (SIED)

A new concept for a fast recovery diode is presented. It is necessary to optimize both the anode and cathode structures in order to realize compatibility of the high reverse voltage, the low forward voltage drop, and the fast and soft reverse recovery characteristics. Based on this concept, the static induction emitter diode (SIED) has been developed. In this paper, the operating mechanism of the SIED is described using simulation and experimental results.
