What shottcky diode do I use?

[stoi2m1]

Im looking for the correct schottky diode to use with a diagram in this datasheet
http://www.techknowman.com/Electronics/MP3_Player/Add%20ons/Digital-Contrast/ds1809.pdf
On figure 3 on page 4 there is a schottky diode and I think the last page of the datasheet calls out the diodes characteristics. Its switching time is 4mS, 2.2 - 1.7 V, and a leakage current of 5u-8uA.

Can someone help me find a schottkey diode I can use in this circuit.

Hi
you could use  say IN5819 series.

In my opinion, in this circuit, you can use any low power schotky diodes or even low power high speed signal diodes.

the voltage drop across highspeed diode is more than that of a schottky diode
the working voltage ,if it is less , we will be adding further voltage drop, thereby reducing the voltage to the actual load. that is why perhaps they prefer to yuse schottky device.
