Huh?  You originally asked about a transistor.  What kind of circuit do you
have where you can replace a NPN transistor with a Schottky diode?

So what does that have to do with the B-E drop of a transistor, which is
what you originally asked about?  It sounds like you want low on voltage.
Why not a FET like IRLML2502, for example?
