I am trying to get an exact part number for this so I can purchase another one immediately. Littelfuses UltraMOV family is as far as I’ve gotten on identification. Any help on getting an exact part number would be appreciated.

Hello,

Welcome to the forum. Well the part number appears to be [V150LA20CP, click here.](https://www.digikey.com/en/products/detail/eaton-electronics-division/MOVTP20V150N/15293354) The part marking is on the data sheet. Though it is on backorder at this time. The closest stocking alternative I can find is part number [283-MOVTP20V150N-ND, click here.](https://www.digikey.com/en/products/detail/eaton-electronics-division/MOVTP20V150N/15293354). You can review datasheet to see if it will work for you.
