FERD20S100S 100 V field-effect rectifier diode Datasheet - production data A Description K The device is based on a proprietary technology K A that achieves the best in class V /I trade-off for a F R K given silicon surface. This 100 V rectifier has A been optimized for use in confined casing K A IPAK applications where both efficiency and thermal A K performance matter. With a lower dependency of A TO-220AB leakage current (IR) and forward voltage (VF) in K K function of temperature, the thermal runaway risk A A is reduced. Therefore, it can advantageously A A replace 100 V Schottky diodes.
