Schottky Diode disadvantage as compared to usual diode [duplicate] Closed 6 years ago. Schottky diode have a low forward voltage drop (typically 0.15 − 0.45 V) and very fast switching action, as compared to traditional diode, which typically have a 0.7 V voltage drop (Silicon diodes) Advantages and Disadvantages of Using Schottky Diode. Advantages. Minimal to zero depletion results in low capacitance in the diodes; Recovery time reduces greatly, especially in a reversed state. The switch on to shut down time lapse is very small. The density of the current flow is higher due to the absence of the depletion layer
Disadvantages of schottky diode Large reverse saturation current Schottky diode produces large reverse saturation current than the p-n junction diode There are some disadvantages to keep in mind about Schottky diodes. A reverse-biased Schottky diode will experience a higher level of reverse current than a traditional diode. This will lead to more leaked current when connected in reverse. Schottky diodes also have a lower maximum reverse voltage than standard diodes, usually 50V or less Schottky Diode Disadvantages. It has a high reverse saturation current. Schottky Diode Applications. There's a long list of Schottky Diode's applications, here I've mentioned a few of them: It's used in radio frequency appliances. It's used in circuits of Logic Gates. It's used in designing rectifiers
Schottky diodes are named after their inventor, Dr. Schottky, and SBD is short for Schottky Barrier Diode. SBDs are not made using the principle of forming a PN junction between a P-type semiconductor and an N-type semiconductor but are made using the metal-semiconductor principle formed by the contact between a metal and a semiconductor. . Therefore, SBD is also called a metal-semiconductor. Disadvantages of Schottky diode The only disadvantage of Schottky diodes is that the reverse saturation current of the diode is large. What is the difference between Schottky diode and PN junction diode
A typical schottky diode may consume only 0.3-0.4V across its junctions. Thus, it saves about 300mV of power. Below is a chart of a schottky's diode forward voltage vs. forward current characteristics: You can see that with a forward voltage dropped across the diode between 0.3V and 0.4V, the schottky diode's current begins to significantly. Schottky diodeis a special type of diode with low voltage. When current flows through the diode will be detained by the internal resistance, which causes a small voltage at the diode terminals . 5 answers schottky diode have a low forward voltage drop typically 015 045v and very fast switching action as compared to traditional diode which typically have a 07v voltage drop silicon diodes Schottky Diode.

Schottky doesn't have reverse recovery time. Ordinary silicon diode can't stop conducting instantly, this is very important in switched power supplies. Lower forward voltage drop of schottky diodes is also important in power supplies, because it wastes less power. Schottky diode reverse breakdown voltages are often a lot lower The Schottky diode (named after the German physicist Walter H.
