Hi,

I would like to put a thyristor with (Ipp=500A 2/10 us) for longitudinal protection( Telcordia G1089-CORE standard) in E1 circuit.
I want to know the number of vias in pcb layout design required to be put for the thyristor pad connecting to the ground for this high current. Is one via enough or multiple vias required?
Please help.

Regards,
Pawan
 

Consult the spec sheet of your PCB manufacturer for electrical characteristics (impedance) of their vias. Since I presume this is a low frequency circuit, the parasitic inductance of the vias is negligible, so the more vias you have in parallel the better.
 

In your case multiple vias with the ground is the better solution.
