Closed Circuit Booster / Limiter diodes ?

[Pimpoftheyear70]

The BOM calls for BAT42 diodes , i don't have any of those .
How important is the BAT42 diode to this build ?
Is there a common diode that can used ?
BAT 46 ??


Any help would be appreciated .
Thx

I would like to ask the same question. I ordered some BAT85 (30V, 0,2A). Are they comparable? Thanks!

Comparing the forward voltage of these Schottky diodes:
Bat42 = 400mV at 10mA forward current
Bat46 = 450mV at 10mA forward current
Bat85 = 400mV at 10mA forward current

All 3 above diodes should have very similar results in this circuit.
