High Voltage Common Cathode Schottky Rectifier STF20100CE

Date:May 03, 2017

The STF20100CE is a 20A, 100V common cathode Schottky rectifier packaged in the ITO-220AB fully isolated package.  The device has a very low forward voltage, VF, drop and low reverse leakage current, IR, resulting in low total conduction losses and enhanced levels of efficiency.  The common cathode configuration and high reverse voltage capability make these devices ideal rectifier solutions for high frequency, energy sensitive applications such as Solid State Lighting (SSL), Power over Ethernet (PoE) or as output bridge rectifiers in switching power supplies (SMPS or DC/DC).  The devices employ guard ring construction for enhanced levels of reliability and robust reverse energy capability.
