Wich type of diode for solenoid ?

[Screech]

I fitting a diode as close as possible to a 5 volt solenoid.

My supplier carries a couple of different types.
Which ones do I use?
High speed Schotty or general purpose ones ??

I have a 1N5819 (1A 40v Hi speed Schotty) and a 1N4004 (1A 400v, general purpose diode ) in my spare parts box.

Thanks.

Use the 1N4004, no need for speed.

Will do. Thanks Nigel.

This was discussed in more detail here:

I believe that the Schottky is also a poorer choice as it's reverse leakage is greater than a 'normal' (like 1N4004) silicon rectifier diode, so it would be consuming current unnecessarialy (as the diode is reverse biased in this application).
