Question
WHAT IS A BASIC DIFFERENCE BETWEEN THYRISTOR,TRIAC AND A 
DIAC.AND WHAT R THERE APPLICATIONS?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Thyrister is semicondoctor device convert the stable dc
to variable dc which has a three terminals
anod ,cathod,gate.
The diac is simelar to thyrister which biddirectional
without gate terminal work on both ac&dc.
the triac is known as diac with gate.

APPLICATION:-
THYRISTOR;-IT USED AT
minehauler,pressmachine,HVDCpawersupply.
In future bracking in automobile,regenrativebraking.

Answer
# 2
thyrister means four layer three terminal semi conductor
devices its unidirectional its use ac or dc
triac means triode working on ac ,triac is a
bidirctional,three terminal devices , main terminal1, main
terminal2, gate,
diac means diode working on ac its two terminals , main
terminal1.terminal2

Answer
# 3
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.

DIAC is a with 2 buttocks... that is why, its called
diac.when a person farts, the dirty and unbearable smell
directly blows out from the in uni direction... and
while doing potty.. especially while the person is having
dysentery or doing liquid potty.. the potty directly flush
out through one direction from the ..

TRIAC is a with 3 buttocks... that is why, its
called triac. when a person farts, the dirty and unbearable
smell directly blows out from the in two
direction... and while doing potty.. especially while the
person is having dysentery or doing liquid potty.. the potty
directly flush out through two direction from the ..
