How to test Programmable Zener Diode TL431.


These little IC look just like a transistor and you find them in almost all Switch Mode Power Supplies. So we need to be able to identify and test these devices in order to be able to diagnose and repair these power supplies

This is how to do it....


I work in collaboration with:
The Electronics Channel (live streams with Carlos and Detlef)
   / @theelectronicschannel  

Gran Canaria Uncovered
   / @grancanariauncovered   (with Detlef and Julie. Not electronics related)
