650V Silicon Carbide Schottky Diodes Wolfspeed 650V Silicon Carbide Schottky Diodes feature zero forward current and forward voltage drop. They also offer a low forward voltage drop (VF), low leakage current (IR), and 4A to 20A current rating. These Schottky diodes are available in standard TO-247-3 and TO-252-2 package sizes. Typical applications for Wolfspeed 650V Silicon Carbide Schottky Diodes include switch-mode power supplies (SMPS), solar, UPS, and battery charging systems.
