Diotec Semiconductor AG

The SIT10C065 and SIT12C065 by Diotec Semiconductor are two neighboured members of the 650 V single diode family in TO-220AC. They offer 10 A respectively 12 A of average forward current. Both are ideally suited for high voltage / high frequency switching circuits, such as Power Factor Correction (PFC), high efficient solar inverters or data server power supplies.

Both device feature a high reverse voltage of 650 V combined with an extremely low "reverse recovery" better say capacitive charge and thus discharging time. That makes it ideally suited for all applications, where high voltage levels are switched at very high frequencies.

In that case, switching losses are dominant; which calls for high efficient Schottky rectifiers. Silicon based types can be done up to about 200 V; this limitation can be nowadays overcome by using Silicon Carbide wafer material.
