FFSH SiC Schottky Diodes onsemi FFSH Silicon Carbide (SiC) Schottky Diodes provide improved system efficiency and have a max junction temperature of +175°C. These onsemi Schottky Diodes have no switching loss and a high surge current capacity. FFSH diodes use Silicon Carbide semiconductor material for higher operating frequency, increasing power density and reduction of system size/cost. This ensures high reliability and robust operation during surge or over-voltage conditions.
