Hello Eric,

I have used sub-circuit statement to generate spice model . The attached statement has been downloaded from supplier website ( littlefuse). Please find this attached notepad for sub circuit statements information.

Thank you Eric.

Yes it looks same.

I would like to understand the effect of placing R5. Is there a need to place TVS after R5. I want to supress a transient in the end. Can you help on this
