    First post. woo

    Im building a power distribution box to power multiple 12v devices it has an input for power from the wall and power from a VCLX battery. Im having trouble finding a diode that seems like it will work. It needs to support max current of 4-5 amps and a max voltage of 16v. Any help would be appreciated ive just been having trouble reading the spec sheets Ive been getting conflicting terminology through google.
    thanks everyone

    thank you. really dumb newb question but based on this i should be looking at the "Voltage - DC Reverse" for my max voltage? I guess ive been getting thrown off by "Voltage - Forward (Vf) (Max)"

    Yes, reverse voltage is the maximum voltage it can block in the reverse direction, forward voltage is the voltage across it when conducting the stated amount of current (the forward voltage varies some with current).

    hmmm ok. I installed the one i mentioned and i got some smoking once i started to put a good sized load on it. I have to check my current again when i get home, but i cant imagine its more that 3amps

    right now its pulling 1.2A @ 150w there are a couple other things i need to plug into it and id like to have some headroom. I think i might possibly need 12amps @ 250w total

    im a bonehead its 12amps at 150w and a possible 20amps at 250w
