The low forward voltage drop, and using metal instead of P-type semiconductor increases the speed of the Schottky diode. The Schottky diode is specially designed with metal replacing the p-type semiconductor for faster switching. (2) Schottky Diodes are used in high-frequency radio transmission applications. Schottky Diode is also used in protection circuits like the Reverse Polarity Protection circuit, because of its low forward voltage drop. The main application of Schottky diode is high frequency switching application. Working of Schottky Diode. Diode - Schottky - Electronic Symbols. Symbol of Schottky Diode. [Main Difference] Between PN Junction Diode and Zener Diode, What is Diode? Each of these diode circuit symbols incorporates the basic diode format, but is modified to indicate the different function.

JIC / NFPA Sample Drawing; IEC 60617 Sample Drawing The forward voltage drop of a normal PN Junction diode is 0.6V to 1.7V. It is a metal – semiconductor junction that does not have the capacity to store charges at their junction. Schottky diode is also used in the diode detector circuit. Capacitors     (3) The Schottky diode has very important applications in switch mode power supply(SMPS). The important applications of Schottky diodes are, (1) Schottky Diodes are used in Digital audio mixer. The switching speed of Schottky Diode is very faster than normal PN Junction Diode. Schottky diodes are used where there is a need for limiting losses and high frequency e.g, in RF applications where there is a need for low forward voltage drop and frequency is also very high. These diodes are also used for rectification purposes. The construction of Schottky Diode is almost the same as PN Junction diode, only the difference is P-type semiconductor is replaced by the metal such as aluminum or platinum.

Diode Symbols [ Go to Website ] 2/3 All Electrical & Electronic Symbols in https://www.electrical-symbols.com The junction capacitance of Schottky diode is ver lower than a normal PN Junction Diode. Op Amp circuits     ▶︎ Rohde &Schwarz Focus on Test Zone. There are many different forms of diode and for most types there is a distinct circuit symbol. As here the p-type semiconductor is replaced by the metal, so the switching speed of the Schottky diode is very high and also the reverse recovery time is very low. Wires, switches & connectors     . Field effect transistors     Power supply circuits     FET circuits     The most important physical parameter of this Schottky diode is their fast switching rate and less forward voltage drop. Circuit symbols overview     Symbol of the Schottky diode is based on generic diode symbol, but instead of having a straight line it has an S like structure at the negative end of the diode as shown below. The following image shows the symbol of a Schottky Diode. For all of these there are distinct circuit symbols. In Schottky diode, the junction is created by the joining of metal and N-type semiconductor material that is why it is called metal-semiconductor junction.     Return to Circuit Design menu . The advantages of Schottky diode over Normal PN junction Diode are high switching speed, no reverse recovery time. In PN Junction diode, the joining point of P-Type and N-type semiconductor called PN Junction. Diode Symbol: Also, you can see the reverse voltage rating of Schottky Diode is lower than the normal PN Junction Diode. . Each of these diode circuit symbols incorporates the basic diode format, but is modified to indicate the different function. How and Why [Zener Diode] Regulate Voltage in Reverse Bias? The Schottky diode has great advantages over PN Junction diode which are explained below. More Circuits & Circuit Design: Although the dode circuit symbols provide the indication of the cathode and anode, these annotations are normally not included on circuit diagrams as they take valuable diagram space and it is assumed the right connections will be understood. Ciircuits, Diagrams & Symbols Includes: Low reverse voltage rating. But the forward voltage drop of Schottky diode is very low from 0.15V to 0.45V. And as the PN junction diode has low switching speed that is why it is not suitable for the high-frequency application. Maximum 200V reverse voltage rating Schottky diode available.
