A dual common-cathode Schottky diode contains two Schottky rectifier junctions with their cathodes connected together and separate anodes. This arrangement can feed a shared positive output from two rectifying paths, as in a suitable center-tapped supply or diode OR-ing circuit. It is not a four-diode bridge or a synchronous rectifier. The shared connection is the … Read more
A trench Schottky diode is a Schottky rectifier that uses a trench-based semiconductor structure to improve the trade-off between forward conduction, reverse blocking and leakage. The important distinction is electric-field management, not a guarantee of zero loss or the smallest forward drop. Its benefit must be assessed at the circuit’s current, reverse voltage, temperature and … Read more
