TVS diodes clamping Voltage is 57V and if I/P voltage > 57 V then diode would burn ?

 

hi L,
Welcome to AAC.
If the current thru the TVS was not limited in some way it would over heat.
Do you have a burn out TVS problem.?

No

Or blow the fuse.

A fuse blowing would limit the current???

It certainly would.

A fuse in series with a TVS diode is the typical way to protect the TVS diode when it conducts due to over voltage.

 

hi dl234,
I was not asking a question about the fuse, I was explaining the point in post#2, ref #3, that A fuse blowing would limit the current.

For eg my input is 40V,35A what range of fuse should I use and TVS diode current rating
