Hi,

Newbie here,, Hopefully the right place to post this?

I am looking for help in identifying a mosfet and finding an equivalent, if anyone can help?

The ID markings are GP640N25S.

Really struggling with this, so any help would be appreciated..

Hi Darren, is it a 40A @250V?
If so, search for a 40N25.

What is the application? It's usually pretty easy to find an alternative using the max voltage/current and gate drive parameters.

Most parts suppliers (like Mouser, RS Components, Rapid, Farnell etc) have parametric search engines where you can simply click on the parameters you need (minimum values - anything HIGHER is usually ok too) and they then offer a sorted list of alternatives.

Hi,

Thank you for your responses.

The application is an inverter, I am currently going through what you have suggested and I have also been lucky enough to find someone in a similar position to me on youtube, so hopefully between both things I should be able to find something..

I think you are on the right lines, it has been suggested to me that I up them to a 51n25. still doing some research but think this could be the ones, thank you.

Hello,

Have a look at the datasheet for specification details.
