About SiC and FERD rectifier technology
Silicon Carbide (SiC) rectifiers
SiC is a wide bandgap material that allows the design of high-voltage Schottky-structured rectifiers with negligible switching losses and high-temperature capability. The fact that the switching losses are dramatically reduced permits improvement in the efficiency of power converters working in hard-switching mode.
Field-effect rectifier diodes (FERDs)
Field-effect rectifiers offer an improved price/performance ratio for low-voltage rectification (up to 100 V). The technology allows the design of diodes with low conduction losses coupled with no switching losses and controlled leakage current. They offer higher reliability and lower risk of thermal runaway compared to Schottky diodes. They also allow designers to reach higher efficiency levels without the need to move to synchronous rectification systems based on more expensive MOSFETs and controllers. ST’s FERDs come in a variety of power thru-hole and SMD packages, allowing for greater design flexibility and high power-integration levels. For each voltage family, various electrical trade-offs are possible to optimize the performance of the rectifier, depending on the application conditions.
