Diode identification

Hi! Servicing a SGI Fuel CPU, I found a short circuited diode. The only marking is S4 15. The companion diode, working, has 0.2V of forward voltage, so it could be a fast recovery Schottky switching diode. Could you help with the marking?

Thanks!

Maybe it is a protection zener of 15 volts? (which blew while protecting?)
