Schottky rectifier

Schottky rectifiers have been used for several years in the power supply industry. The primary advantages are switching speeds that approach zero time and very low forward voltage drop. The reverse recovery time of Schottky diodes provides extremely fast recovery characteristics.

Een schottkydiode is een halfgeleiderdiode die bestaat uit een overgang tussen een metaal en een n-gedoteerde halfgeleider in plaats van de gebruikelijke pn- overgang in een gewone halfgeleiderdiode. De schottkydiode is genoemd naar de Duitse natuurkundige Walter Schottky. De gelijkrichtende werking van een . The Schottky diode also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. For Silicon devices, the forward voltage drop of the pn-junction rectifier can not be reduced below about 0. In the case of the output . ON Semiconductor supplies low-loss and high current schottky diodes and rectifiers.

This latter feature has also stimulated their additional use in very high . Packaged in ISOTOP, this device is intended for use in medium voltage operation , and particularly, in high frequency circuitries where low switching losses and low . Mode Power Supply and high frequency DC to. Typical applications are in disk drives, switching power supplies, converters, freewheeling diodes, battery charging, and reverse battery protection. The devices feature an extremely small, low profile package and have very low thermal and electrical resistances.

The SHD packages contain no magnetic elements. Features, Specifications , Alternative Product, Product Training Modules, and Datasheets are all available. It is packaged in the hermetic isolated TO-257AA package. Free wheeling diode in low voltage converters.
