Frequently Asked Questions (FAQs)
1. Are Schottky diodes silicon?
The most common contact metal used for Schottky diode construction is “Silicide” which is a highly conductive silicon and metal compound.
2. What is the difference between a silicon diode and the Schottky diodes?
Schottky generally has lower reverse voltage max. You can easily find silicon diodes with 20-1400v ranges, while commonly schottky is 20v-60v. Schottky is extremely fast recovery, even faster than so-called “fast recovery” silicon diodes. So you can use them in high frequency SMPS.
3. What is Schottky diode used for?
Schottky diodes are used as switches in fast-clamp diode applications. In this application, the base junction is forward biased. With Schottky diodes, the turn-off time is significantly reduced and the speed of the circuit is increased.
4. Are Schottky diodes better?
Better performance. 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.
