    Default High sided driver question

    Im after a yes or no anwser here not a massive debate.

    with a 445 diodes the pins arent connected to the case so a high sided driver is not needed as such and it cant die from static by touching the case. you have to touch the pins.

    with open can red diodes and pins are connected to the case, so we need a high sided driver. but does a high sided driver offer any additional protection from static by touching the case?

    Nope no additional protection really

    Good grounding practise is going to guard against static if the diode is built into a module and in a projector..

    thought so.

    having to isolate diodes from base plates is a pain in the arse

    The way round this problem with reds is to use the Optnex 638nm diodes as they are isolated pins like 445 diodes but somewhat more pricey than the 815 LOC reds.

    if you use TECs and plastic screws to hold a diode array to the baseplate then the isolation part becomes much more simple me thinks.

    that is what i am going to do anyway. throw in a couple of tecs andy, even if you won't be using them in the immediate future

    you could use many of these then

    two for each through-hole-screw. should do the trick without using TECs
