How Optocouplers work - opto-isolator solid state relays phototransistor

День тому

Optocoupler. In this video we learn how optocouplers work and also look at some simple electron circuits you can make yourself to understand how an optocoupler, opto-isolator, phototransistor, photocoupler works. Photo transistor
Correction 13:21 Upper text "220Ω" resistor should say "22Ω" calculation in lower screen is correct

Hey, much appreciated. I say this because I do maintenance for XPO and Holland freight and we do knock out where we remove c channel from concrete and jackhammer concrete and repour and weld dock plate and bumpers. A lot of work but definitely appreciated by those forklift drivers n truckers to keep production going. Good job n forgive me for grammar.

I have been retired for 3 years. I had to understand schematics and digital circuits as wells as pumps and motors for my job in power plant operations. I was not trained formally as an electrician. I knew what I didn't know but I could understand what I needed to know for personal and plant safety. However, I never understood enough that I could explain it or teach somebody else. I wish I was trained with these videos 30 years ago because they are so clear compared to drawing in a text books. May be then I could explained how things worked better because I knew things did work.

I can't tell you how grateful I am for making these videos; I have a hard time accepting "this does that" without an explanation of the underlying foundations of why it "does that". Your explanation down to physical properties of the material is precisely what makes me go "oh! that's why!" and what I've been looking for all this time I've been trying to learn electronics. Keep up the amazing work and thank you!

@drlegendre Рік тому

When discussing optocouplers, it's a good idea to mention Vactrols aka resistive optoisolators. They aren't ofren used these days in new designs, but in the past they were widely used in audio gear like guitar effects and analog synthesizers. Since these are both popular topics, DIYers are likely to encounter the Vactrol sooner or later.

Very complete and concise presentation. I noticed one thing about PC817 though that surprised me. You show the pins 1, pin 2 on one side and pin 3, pin 4 on the other. According to the Sharp datasheet, pin 3 should be pin 4 and pin 4 should be pin 3. That is, the pins are numbered down one side and up the opposite side, not both sides from top down. Not sure that will cause anyone too much heart burn, but ...
