Sanken Electric has expanded its lineup of SiC Schottky diodes. The new FMDA-10565 SiC Schottky is rated for 650V and 5A with a typical forward voltage drop of 1.5V at 25 degrees C. Taking advantage of the high speed switching capability of SiC, these diodes achieve reduced switching loss, and reduced reverse leakage current at high temperatures. At 25 degrees C, typical leakage current is 15 µA at a junction temperature of 150 degrees C, typical leakage current is 70 µA.
The FMDA-10565 is designed for use in PFC sections, motor drive circuits and inverters in applications such as servers, communications power equipment, air conditioners, and so on. Packaged in a TO220F-2L, these Schottky’s have a temperature coefficient of 2.5 degrees C/W and an operating junction temperature range of -40 to 175 degrees C.
These devices are particularly well-suited for continuous current mode PFC circuits. They are capable of reducing the power loss that results from the recovery current. The diode’s high-speed switching capability and energy-saving functionality allows for the potential downsizing of equipment. The 5A FMDA-10565 is the third device in this family and it joins the 10A FMCA-11065 and the 20A FMCA-22065.
