Abstract
A pin diode includes an inner zone, a cathode zone and an anode zone. A boundary surface between the inner zone and the anode zone is at least partly curved and/or at least one floating region having the same conduction type and a higher dopant concentration than in the inner zone is provided in the inner zone. The turnoff performance in such geometrically coupled power diodes, in contrast to the turnoff performance of pin power diodes (in the Read-diode version) with spaced charge coupling, is largely temperature-independent. Hybrid diodes with optimized conducting-state and turnoff performance can be made from such FCI diodes. FCI diodes are preferably used in conjunction with switching power semiconductor elements, as voltage limiters or free running diodes.
