    How to install Diodes

    I picked up a diode from Radio Smack the other day so I could wire it to prevent backflow of power. This thing is a LOT smaller than I thought it was. What is the best way to wire it in? Can it only be saudered? It's so small, I'm afraid to break the little thing. What have you guys done to wire yours in?

    methinks you got the wrong diode.

    What are you using this diode for?

    As the wiz sez, you need to make sure your diode can handle the power. Being small, it might not be able to handle much.

    Yes, soldering is the way to go.

    is your diode black with a silver stripe? or clearish looking red (germanium..oops). If it is the black one, it will have polarity instructions on the back, and if it is small you probably will need to parallel a ton of them to get them to hadle the kind of amperage that we are dealing with or you may let the smoke out of the box

    The diode is small, but it's the same one (1N4001) suggested in this thread. You guys think it's not enough? Am I missing something?

    I will try to not make a comment that will get me into another flame war, but some people in that thread do not know what they are talking about. If you are building a tank circuit for a car PC, you need a bigger diode.

    Alright, so which diode would you suggest and why?

    One that handles enough amps. What answer do you want for why?

    You still haven't specified what it is for, is it a tank circuit? If so, disregard most everything in that thread and do some searching in the Power Supply subforum.

    I buoght the 12VDC 5.1Ah Nickel Cadium recharable battery from TheSpecialist for my ITPS to allow it to survive a crank. I'm running the ITPS to a PW70a attached to an EPIA M10000. How many amps do you think the diode would need to handle for my setup? I appreciate the help, I'm still learning..

    I have the exact same setup and it is working perfectly.

    I am using a 1n4004 diode on my tank circut and it does survive cranks.

    The main battery drops bellow 8v but the second battery keeps a constant 13v while I crank the car.. No problem at all. I am also using a ITPS but not for what it is supposed to be used for (shutdown controller)
