Chauffeur overdrive -yet another diode question... 1n5819

Can I use a 20v 1n5817 instead of the 40v 1n5819 ?

There's no schematic yet for this one, but a little continuity check later I found that it's directly connected to the +9v pad so I am pretty sure it's a polarity protection diode.

Just wanted to make sure before finishing up this pedal ! Thanks !
 
While both the 1N5817 and 1N5819 have the same Fvd, their respective RMS reverse voltage ratings are different. The 1N5817 will fall into reverse protection at ~14v while the 1N5819 will fall into reverse protection at ~28v. So the 1N5819 will still work.
