ALTTERNATE TO csd 18532(n channel power mosfet)

I m trying to do multiple input and multiple out using light as the medium of communication but i could not find the the mosfet named CSD 18532(n channel power mosfet). i could not find its use in other electronic device. Can u help me out of it.

What do you want to switch.
There are probably hundreds of other logic level mosfets that could replace this fet.

Wawa is right, but if you really want that particular MOSFET, 'Mouser' have them:- CSD18532KCS
