Identifying a TO220 device

[Nevillet]

Hi All,

I'm trying to repair a swich mode PSU and have found a shorted TO220 device but cannot track it down.

The markings are:

First
15T43
FIR7N65AF

A picture is attached.

Many thanks.

Likely the same as FIR7N65FG

Many thanks for that. Best wishes,

Google something like 7n65 and you will get tons of results.
