WHAT IS A BASIC DIFFERENCE BETWEEN THYRISTOR,TRIAC AND A
DIAC.AND WHAT R THERE APPLICATIONS?
Answer Posted / abid mirza
Thyristor means is a 4 layer device with two terminals ,
the anode and the cathode. The main diff is the silicon
controlled rectifier.
The diac means it has two terminals A1 , A2. It conduction
occurs in a diac when the breakover voltage is reached with
either polarity across the two terminals.
The triac is like a diac with a gate terminal it's mean
three terminals. A triac can be turned on by a pulse of
gate current and does not require the breakover voltage to
initiate conduction.
