Sanken’s FMKS-2000 series is an ultra-fast recovery diode (200 V reverse voltage) series with an SBD formed on the same die. This makes it possible to detect over-heating caused by over-current (temperature increase of built-in FRD). By using the FMKS series, consideration for thermal connection is not necessary. The FMKS series is targeted at consumer equipment (white goods, audio and visual, lighting equipment), industrial equipment (telecommunication equipment, FA), and for secondary-side rectification of switching power supply.
