The principle advantage of Schottky barrier rectifiers is a very low forward voltage, for example 0.372V on a 100V, 50A version (2 x 25A common cathode) in a TO-247AD package. Power losses are reduced, and this results in lower heat dissipation and a more efficient power supply. Significantly improved transient characteristics compared to conventional Schottky planar rectifiers is another argument
if favor of the new technology.
Synchronous rectification on the secondary side using MOSFETs can significantly reduce power losses in telecommunications systems, industrial power supplies and distributed power systems. However, these devices are expensive and require appropriate control electronics. This complicates the design and drives up production costs.
