There are quite a few different types of semiconductor diode from junction diodes, Schottky diodes, Zener diodes etc. You need to know the difference between them in order to select one. A good place to start the description of the types would be a comparison of a conventional PN junction diode and a fast recovery […]

Less famous attributes of Schottky diodes
Schottky diodes are useful in some power-converter topologies, especially for shunting the body diode in a half-bridge’s low-side MOSFET. In this position, the Schottky diode prevents the body diode from turning on, particularly when driving inductive loads common in power converters, because it’s forward voltage drop is smaller than that of the body diode’s PN […]
