Schottky Diode Help

[rukiddingme]

Hi all,

wikipedia article on Schottky diodes states:

A normal diode has between 0.7-1.7 volt drops, while a Schottky diode voltage drop is between approximately 0.15-0.45 volts. This lower voltage drop can provide higher switching speed and better system efficiency.

I have looked everywhere to find Schottky diode with a voltage drop of .15-.45, but I can't find any anywhere.

Can I ask if anyone knows where one can get Schottky diodes with a .15 voltage drop?

Thanks in advance.

hello
the bat 46 and the rk44 will do what you want
the bat46 is a 100 volt diode and the rk44 is a 40 volt
the 0.25 FV on the datasheet is the max use
here is a place that has the almost rare bat46

and the rk44

@rukidding

At what current level do you want .15V voltage drop?

At what current level do you want .15V voltage drop?

It's a guess, but an amp give or take a half amp.

Yep, the RK44 looks like exactly what I want. I'm at 10 -15 volts so I don't need 100 volts. Where did you see the forward drop spec for the RK44?
