[sdiy] Diodes, with high Vf?

[Ken Stone]

>Usually a diode has Vf of 0.3-0.6V a LED has 1.2-2,2V,
>Are there any cheap single regular diodes that have like 2.5-3.3V Vf ?

In a word, no. Zeners are what you should be looking at, and if you really
want it to conduct in a single direction, use a regular diode in series with
it, and select a zener voltage that is around 0.6 less.
