MOSFETs can get complicated as you try to model how well they "translate" signal. an Idea MOSFET translates a signal perfectly, or exactly as you want it to be translated, however in the realworld depending on the configuration and materials, the MOSFET has a certain response to different types of signals such that it's wise to characterize the signal you give it and find a mosfet that's rated for the best response in that range.

Now compare that with an Optoisolating Triac Driver that also might get wired up the same way as a MOSFET, but does a different job. It's meant to protect on curcuit from another.

MOSFET versus Optoisolator Triac Driver

just took a bunch of MOSFETs off some old mother boards.

So what's the difference between a MOSFET and an Optoisolator Triac Driver?

A MOSFET can take a small voltage signal and make it large or vica versa, take a large voltage signal and make it small.

not that it might be appropriate to use a different type of MOSFET to convert an analog versus a digital signal.

There are n-type MOSFETs and p-type MOSFET, don't know the diff just yet.

MOSFETs can get complicated as you try to model how well they "translate" signal. an Idea MOSFET translates a signal perfectly, or exactly as you want it to be translated, however in the realworld depending on the configuration and materials, the MOSFET has a certain response to different types of signals such that it's wise to characterize the signal you give it and find a MOSFET that's rated for the best response in that range.

Now compare that with an Optoisolating Triac Driver that also might get wired up the same way as a MOSFET, but does a different job. It's meant to protect on circuit from another.

Here is an example where a doorbell signal controls a camera shutter

MOCO 3020 Optoisolator Triac Driver - Media:161-12855-0-MOC3010.pdf

the idea I think is that the signal from doorbell is isolated from the shutter control. I play in software alot , so I might liken it to input validation.

You are proecting the delcate camera bits from the door bell bits.

Resistor Guide

So I did some testing with my own multi-meter. I moved the meter's dial from 2000k Ohms, Through 200k, 20k, 2000, all the way to 200 Ohms before I got a reasonable reading from my first resistor. I tested yellow purple gold gold, expecting to get 4.7 Ohms, I got 5.5

  • yellow 4
  • purple 7
  • gold "more the decimal to the left by one.

I test brown green gold gold expecting 1.5 and got 2.5 Ohms. (again with the multi meter dial at 200 Ohms)

  • brwon 1
  • green 5
  • gold "more the decimal to the left by one.

I then tested the multi meter on it's own, simply connecting the two leads and got 0.8, this explains the discrepancies good enough for me.

Next resistor: brown green purple gold ( 1 5 7 ).. I get 151 oms.

I expect 15 0000000 but that can't be right. Violet? Purple? I can't tell, I'm blind.

Next yellow purple black black, 4 7 0 mulitple 0 = 470 Ohms, and that's what I get, SCORE.

brown black brown gold - 1 0 1 = 100 Ohms as meaasured ( dial at 2000 ).
