Fuji Electric Corp. of America Rectifier Diodes, Type SBD Model: YG878C20R

The Ultra Low-IR Schottky-Barrier Diode (SBD) guarantees junction temperature of 175°C. Compared with the conventional low IR series, it offers equivalent VF while IR is reduced to 1/10, or less – enabling a reduced risk of thermal runaway and enhanced reliability at higher temperatures. The Super Low Loss Diode (LLD) series for PFC circuits is an improvement in the VF-trr trade-off line of the conventional type. As a result of having a balanced shorter trr with a lower VF than the conventional Super LLD-1 for CCM-PFC, the Super LLD series has a restrained temperature rise and low loss of MOSFET + Diode.
