        Switching diode is a type of semiconductor diode that is specially designed and manufactured for "on" and "off" on a circuit. "It takes less time to change from conduction to cutoff or from cutoff to conduction than ordinary diodes, such as 2AK and 2DK series, and is mainly used in electronic computers, pulse, and switching circuits.".

        Schottky diode is named after its inventor, Dr. Schottky. SBD is short for Schottky Barrier Diode (SBD). SBD is not made using the principle of forming a PN junction by contacting P-type semiconductors with N-type semiconductors, but using the principle of forming a metal semiconductor junction by contacting metals with semiconductors. Therefore, SBD is also known as a metal semiconductor (contact) diode or surface barrier diode, which is a hot carrier diode.

        Zener diode. Using the phenomenon that the current of the PN junction can change in a large range while the voltage remains basically unchanged in the reverse breakdown state, a diode is made to stabilize the voltage. "This diode is a semiconductor device that has a high resistance until the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance decreases to a small value, and in this low resistance region, the current increases while the voltage remains constant. Zener diodes are classified based on the breakdown voltage. Due to this characteristic, Zener diodes are mainly used as voltage regulators or voltage reference elements.". Zener diodes can be connected in series for use at higher voltages, and higher stable voltages can be obtained by connecting them in series.‍
Fast recovery Diodes

Fast recovery Diodes

        Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in electronic circuits such as switching power supplies, PWM pulse width modulators, frequency converters, etc., and is used as a high-frequency rectifier diode, freewheeling diode, or damping diode. The internal structure of a fast recovery diode is different from that of a common PN junction diode. It belongs to a PIN junction type diode, which adds a base region I between the P-type silicon material and the N-type silicon material to form a PIN silicon wafer. Due to the thin base region and low reverse recovery charge, the fast recovery diode has a shorter reverse recovery time, lower forward voltage drop, and higher reverse breakdown voltage (withstand voltage).

A rectifier diode is a semiconductor device used to convert alternating current into direct current. Rectifier diodes are mainly used in various low-frequency half wave rectification circuits. If full wave rectification is required, it needs to be connected into a rectifier bridge for use.
