Schottky diode

Schottky diode is named after its inventor, Dr. Schottky. SBD is short for Schottky Barrier Diode (SBD). SBD is not made by the principle of PN-junction formed by the contact between P-type semiconductor and N-type semiconductor, but by the principle of metal-semiconductor junction formed by the contact between metal and semiconductor. Therefore, SBD is also known as metal-semiconductor (contact) diode or surface barrier diode. It is a hot carrier diode.
