Answer / nithyalakshmi
the angle of rectification can be set in scr but not in
diode .
Is This Answer Correct ? | 63 Yes | 12 No |
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.

SCR has a high voltage handling capacity as compared to a diode
Is This Answer Correct ? | 49 Yes | 13 No |
Answer / vinoth
diode is a 2 terminal device.
in scr gate controls the rectifing
Is This Answer Correct ? | 43 Yes | 9 No |
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.
Is This Answer Correct ? | 47 Yes | 21 No |
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.
Is This Answer Correct ? | 27 Yes | 9 No |
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
