Schottky diode
Schottky diode: A Schottky diode is similar to a silicon diode but has much higher switching speed. It is mostly used in converting alternating current (AC) to direct current (DC).
Full bridge rectifier
Full bridge rectifier: An electronic component that uses four diodes to convert alternating current to direct current.
Zener Diode
Zener Diode: this diode allows current to flow in both directions but until reaching the Zener voltage. used in voltage regulators.
Photo Diode:
Photodiode: a diode that converts light energy to electrical energy. It is used in solar panels and infrared remote receivers.
