What is a Schottky Diode? How Schottky Diodes Work? Where to Use? ( Schottky Diode Tutorial)
Published 2022-04-06
In other words, they cannot change from a conductive state to an insulating state or from an insulating state to a conductive state. Schottky diodes are produced to be used in computers, RF and rectifier applications that need high switching speed in order to respond to these rapid changes.

Great refresher for someone like me who originally learned about Schottky diodes 40 years ago but has forgotten most of the details. Thank you!
-
No mention of the turn-off characteristics of both diodes. Transition from conduction to reverse is the biggest advantage in using the Schottky diode. Usually in power conversion circuits where the Schottky diodes much higher reverse bias current is a negligible negative factor. It was a good beginner's guide tutorial!
-
Disadvantages: 1. breakdown voltage measured in tens of volts vs hundreds of volts. 2. much higher reverse leakage
-
The last part about solar panels is not quite demonstrated properly because the bypass diodes are connected across each individual CELL of a panel, so as to bypass any cells of the overall panel that may get shaded by something like a tree or something at certain times of the day. It wouldn't be nearly as effective if the diodes were only connected across entire panels. Each cell in a solar panel produces about 0.5-0.6 volts in full sun, but goes down very quickly if shaded, so a panel that is only partly shaded will benefit from having ONLY the individual cells that are in the shade bypassed, and still be allowed to have the cells that are still in the sun producing power.

It would've been nice to point out not just the advantages but also the limitations of the Schottky diodes. For example they are much more limited in maximum reverse voltage, than pn diodes.

Finally, some good tutorials that I was looking for. Thank you for your videos.

Excellent Explanation
-
concius and didactical. Very practical and objective. If you ever wanted to know how a smart and clever person is, here is the example. GREAT !!!:trophy-yellow-smiling:
-
Very informative, thank you.
-
Great! I'm working on my amateur extra ham radio license and this is exactly what I needed to learn. Thank you.
-
Really nice. Thanks from Bangladesh.

As a beginner to understand Schottky diod , it was very clear to understand the teacher . You are great . Life is good π Thank you π π€ π¦ β€ππ namasteππ 1 / 17/ 23

you can also get 'ultrafast' diodes of fairly standard construction, such as UF5401, BYV96, same drop as normal types but almost as fast as schottky
-
Excellent!
-
Schottky diodes work well at high frequencies, it's true, but they have too high a barrier capacity, much higher than the old glass germanium diodes with point contact, which also perform very well at equally high frequencies, without the signal being short-circuited of their capacity as the others do.
-
I do appreciate the soft simple way of the technical explanation that you are illustrated at the channel, and for sure this way is not even available in the engineering school itself .... thank you so much πππ .... keep going ππ
-
The world's best teacher so nice and educative
-
No mention of the disadvantage of Schottky diodes compared to conventional silicon diodes with regard to reverse leakage current.
-
Helpful, Thanks sir.

Thank you for your video. Thanks to commenters.
