LER #350 Let's take a look at Thyristors, otherwise known as SCR, and closely related semiconductor devices Triacs and Diacs from the point of view of a repair technician. These fairly common components are often misunderstood so let's clear the fog and learn all you need to know about Thyristors and their closely related cousins to fix stuff!

If you would like to see how to check a Thyristor or Triac has gate drive using a multimeter, check out this short video https://www.youtube.com/watch?v=yhtUYHs9knM
