I am a noobie at electronics and thought I understood MOSFET's and how they work. Then someone said they were using a DIAC and a TRIAC in a sped controller. They looked like they were performing the same function as a MOSFET. Can someone enlighten me (gently)?

What is the difference between a MOSFET and a TRIAC?

Don't forget the middle ground IGBTs
