FERD40H100S Datasheet 100 V, 40 A field-effect rectifier diode Features A K A ST patented rectifier process Stable leakage current over reverse voltage Low forward voltage drop K High frequency operation ECOPACK 2 compliant A A K A Applications K A TO-220AB TO-220FPAB Adapter Gaming console power supply K Battery charger DC / DC converter K A A DPAK Description This single rectifier is based on a proprietary technology, enabling to achieve the best in class V /I for a given silicon surface. F R 2 Packaged in TO-220AB, TO-220FPAB and D PAK, the FERD40H100S is optimized for use in confined applications where both efficiency and thermal performance are key. With a lower dependency of leakage current (I ) and forward voltage (V ) in R F function of temperature, the thermal runaway risk is reduced. It is highly recommended to be used in adapters and chargers. Product status FERD40H100S Product summary Symbol Value I 40 A F(AV) V 100 V RRM T 175 C j(max.) V 0.325 V F(typ.)
