Answer / rasmi ranjan das

SCR means Silicon control rectifier ie it is a 3 terminal
controlled device where as Diode is a 2 terminal uncontrol
device

Answer / harish reddy

Rectifier using scr is a controlled rectifier .
but
rectifier using diode is an uncontrolled Rectifier.

Answer / nithyalakshmi

the angle of rectification can be set in scr but not in
diode .

Answer / shweta

SCR is a controlled rectifier wheras diode is a simple
rectifier, In SCR the gate current controls the firing of
SCR wheras in diode no gate currnt is required for its
control thats why silicon is known as silicon controlled
rectifier.

Answer / sumeet sonigara

SCR has a high voltage handling capacity as compared to a diode

Answer / vinoth

diode is a 2 terminal device.
in scr gate controls the rectifing

Answer / sakthivel.n

SCR is used in High frequency applications but diode is low
freuency devices, SCR can be in high temparatures but not diode.

Answer / thyristor

LET'S SUPPOSE WE HAVE A SINE WAVE[ALTERNATING CURRENT/AC
VOLTAGE]....

IN ORDER TO CONVERT THIS AC VOLTAGE TO DIRECT VOLTAGE WE
USUALLY EMPLOY A DIODE RECTIFIER TO DO THE JOB. THIS DIODE
WILL CONDUCT THE CURRENT NEARLY 180 degrees INTO THE LOAD,
WHEREAS A SCR WILL CONDUCT FROM THE MOMENT IT GETS A PROPER
IMPULSE ON ITS GATE. SCR MAY CONDUCT THE CURRENT ANYWHERE
BETWEEN 0....180degrees, THAT'S WHY IT IS CALLED SILICON
CONTROLLED RECTIFIER, OR THYRISTOR.

Answer / hari patel

SCR is POWER electronics device which can be operated at
high power.Where as diode is simple electronics device.

Answer / anudeep

ACCORDING TO MY KNOWLEDGE SCR IS A THREE TERMINAL THREE
JUNCTIONED DEVICE WHICH IS USED TO RECTIFY AND TO CONTROL
THE BFLOW OF CURRENT.BUT WHERE AS THE DIODE IS USED ONLY
FOR THE RECTIFICATION PURPOSE
