Re: Diodes in parallel to increase maximum current ?

Hi..
Is it possible to place 4 diodes in parallel to increase the maximum
current ?
In this case it would be 4 times 1N5408 diodes.

Well, you could put them in parallel, but it wouldn't serve your purpose.
The reason is that each diode will likely have a different Vf. The diode
with the lowest Vf will conduct first, possibly not allowing the others to
turn on. The diode with the lowest Vf will hog current, possibly to the
point of destruction, probably shorting, thus creating havoc with whatever
lies downline. If it fails open, then the diode with the next lowest Vf
conducts and repeats the cycle. A losing situation either way.
Solution is to get the correct diode.

Cheers!!!
