Diode id on a reverse engineered circuit.

Can someone help be specify a diode for this circuit. I have a Schematic but no value for the Diode.

How do you specify a Diode for a circut?

Is an op-amp circuit that gets its power from arduino and inputs the analog signal into the arduino.

thanks, john

That's most likely a small signal diode like a 1n914.

I agree. The circuit is a peak detector with a slow decay. No need for anything more robust.
