stoi2m1 Posted November 18, 2006 Report Share Posted November 18, 2006 Im looking for the correct schottky diode to use with a diagram in this datasheethttp://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.

mvs sarma Posted November 18, 2006 Report Share Posted November 18, 2006 Hiyou could use say IN5819 series. Quote Link to comment Share on other sites More sharing options...
ElectronicsGeek Posted November 19, 2006 Report Share Posted November 19, 2006 In my opinion, in this circuit, you can use any low power schotky diodes or even low power high speed signal diodes.ElectronicsGeek Quote Link to comment Share on other sites More sharing options...
mvs sarma Posted November 19, 2006 Report Share Posted November 19, 2006 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.
