Suitable Diode 14N48 Replacement?

Hi everybody,

This project is going to be my first foray into modifying electronics, so hopefully I'll be less green by the next time you see me.

Yeah, pluggy, the diode is on that site. :*

In the specs that I linked to, I had read that it was a switching diode and that kind of led me down a garden path. It was filed under another heading. All's well that ends well, I suppose.

Thanks everyone.
