What is a Schottky Barrier Diode? Defination of a Schottey Barrier Rectifiers




The Schottky diode, named after its inventor, also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. Schottky barrier diode not only  have many applications in today's high tech electronics scene,but also it is one of the oldest semiconductor devices in existence.

It has a low forward voltage drop, a switching speeds that approach zero time and is an electronics component that is widely used in RF applications as a mixer or detector. Also used in power applications as a rectifier, again because of its low forward voltage drop, it lowers the levels of power loss, compared to ordinary PN junction diodes.

The reverse recovery time of Schottky diodes provides extremely fast recovery characteristics. What little reverse recovery time they exhibit is dictated by their capacitance instead of minority carrier recombination such as in conventional PN junction rectifiers. This offers very little reverse current overshoot when switching the Schottky from a forward conducting mode to a reverse blocking state.




Most stronge Fast Recovery Diode in WEET are SMA Schottky Barrier Rectifier SS12-SS110, SMB Schottky Barrier Rectifier SS32-SS310, SMC Schottky Barrier Rectifier SS52-SS510
