Recommendations for a general schottky diode?

[Dan123456]

Hey there 

Was just browsing through Digikey as need to place an order for some bits and pieces and got to looking at schottky diodes.

As I don’t have any in my stock pile currently, I figured grabbing a few might not be a terrible idea?

That said, I have no idea what is what here so thought I’d pick your guys brains first 

For some general ones just to have on hand, should I just grab a hand full of cheap 100V 1A ones?

Sorry in advance for what is probably a dumb question! I wan’t sure if this is a 1N400X situation where just grabbing the highest voltage option is best, or if this is another inductor situation and I shouldn’t bother until I actually need it and then pick the one to suit the application type deal 

Thanks once again for your time all

Higher voltage rating also comes with higher forward voltage.

Usually when you want a Schottky is either because you want either low voltage drop or a fast diode.
Schottky diodes over 100V are less commonly used.

If you want low voltage drop then you also need to consider the max voltage of the diode because the really low voltage drop diodes are also low voltage diodes.
 
eg with the popular 1N5817,1N5818,1N5819 series you can see in the datasheet as the voltage drop gets lower/better the max voltage also gets lower.

The 1N581x series is a good diode to have around,  I normally just get the 5819 version since its more useful for a wider range of things, up to like 24V rails with some good safety margin

Ah perfect!

Thank you so much 

I was only thinking about the fast recovery side and hadn’t thought about the low voltage drop uses!

Looks like the 1N5819’s are the winner’s as a general purpose Schottky then

There's probably something newer/better, but the 1N581x is a jellybean part.

You can get diodes with even lower voltage drop than the 1N5817 for really low voltage stuff, like under 5V.

But yeah, everyone should have a supply of 1N5819 and 1N4007 diodes to cover schottky and normal. 
1N4148 is another general purpose jellybean fast diode for low current stuff.

Also useful to have some higher current diodes, like 3A in both schottky and normal, if you think you might need them.
