What shottcky diode do I use?

Recommended Posts

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.

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.
