What is the main purpose of a Schottky diode in semiconductor applications ?
High-speed switching
A Schottky diode is a metal–semiconductor junction. Current is carried almost entirely by majority carriers (electrons in an n-type device), so there is practically no minority-carrier charge stored at the junction.
Because no stored minority charge has to be removed when the diode is switched off, its reverse-recovery time is extremely small (picoseconds to a few nanoseconds). It also has a low forward drop (about 0.2–0.4 V).
These properties make it the device of choice for fast switching – clamping in Schottky TTL, high-frequency rectifiers in SMPS, RF mixers and detectors.
Voltage regulation is the job of a Zener diode, temperature sensing uses thermistors or ordinary p-n junctions, and a two-terminal diode cannot provide power amplification.
Hence, the main purpose of a Schottky diode is High-speed switching.
