Schottky Diodes

Schottky diodes use a piece of metal against the N-type side instead of a P-type semiconductor. This results in a much lower voltage drop and fast switching speeds and are oftenused in a clever way to get to a digital 0/OFF. Used for basic logic control.

The circuit symbol for a Schottky diode looks similar to the diode symbol, except that the perpendicular line looks similar to an S.

Schottky diodes typically have a very low voltage drop (Vf), typically around 0.2V (0.15V to 0.45V) which makes them very fast and also makes them ideal for use in simple circuit logic.
