From Avalanche to Zener, we have diodes for you today! Learn how diodes work and how to use them in your circuits. Laser Diodes included!
Diodes have been around for a very long time. They were the first tube devices and the first semiconductors, and today, there are many different types of diodes for many applications.
We’ll look at several types of diodes today. We’ll see how they are used and perform a few experiments with them. Not only that, but we will also take out a few Laser diodes and play around with them.
Here is a list of the diodes we will be learning about:
Rectifier diodes
Switching Diodes
SCRs (Silicon Controller Rectifiers)
TRIACs
DIACs and SIDACs
Zener Diodes
Avalanche Diodes
Tunnel Diodes (Esaki Diodes)
Varactor Diodes (Varicap Diodes)
Schottky Diodes
PIN Diodes
Shockley Diodes
Photodiodes
LASCRs
Opto-TRIACs
LEDs
Laser Diodes
That's a lot of diodes, and each one is unique!

There were quite a few in there I didn't know about. Very informative.
First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

Zener diodes are something I've come across while I research something I want to build, so this is great timing as an introduction to diodes!

From my comment that I posted on the 'Video', before I became registered here:

Bill,
Thank you so much for this guide. I learned, not only what you set out to teach, but also a little more about how useful a tool a Scope is here.
Being very new to the topic of Electronics, this is exactly the kind of thing I was hoping that you would be doing and I very much look forward to learning much more from you.
