WNSC Silicon Carbide Schottky Diodes WeEn Semiconductors WNSC Silicon Carbide (SiC) Schottky Diodes are optimized for use in high-frequency switched-mode power supplies. SiC devices provide many advantages over silicon, including no reverse recovery current, temperature-independent switching, and excellent thermal performance. These features result in higher efficiency, faster-operating frequency, higher power density, lower EMI, and reduced system size and cost. WeEn Semiconductors WNSC Silicon Carbide Schottky Diodes are offered in TO-220-2, TO-247-2, and TO-247-3 packages and are lead free, halogen free, and RoHS compliant.
