The ST30200C and STB30200C devices are dual, common cathode, high power dual Schottky rectifiers available in industry standard TO-220AB and D2PAK packages, respectively. The very low forward voltage, VF, drop and low reverse leakage current, IR, result in low total conduction losses and enhanced levels of efficiency. The very high reverse voltage capability of 200V makes these devices well suited for higher voltage switching supplies, Solid State Lighting (SSL) and power industrial applications. The common cathode configuration facilitates use as output rectifiers in high frequency switching supplies and DC-DC converters. The devices employ guard ring construction for enhanced levels of reliability and robust reverse energy capability.
