decifer diagram?

Yes I have I was installing them in a car Amplifier and it didn't work. 

I found out from the school of hard knocks that you must wear a grounding strap and absoloutly no wool or poly.

I tried to return them to the electronics store I bought them at and they ended up selling me this rinkey dink wrist band with a  wire and clip. I ended up making my own by wraping some wire around my metal band flexable wrist watch and running a wire to a water pipe.

Most houses these days have plastic pipes so I had to run a 4 ft rebarb into the ground and tie the other end of the wire to that.

Another easy way is to wrap a strand of wire around all of the pins before you solder it into the board and unwrap the wire after it is soldered in. I also use a grounded soldering iron.

I guess that I am a permanent ground.  I have even tried to zap them with no luck, walking across the carpet  charging my body and then touch the device.  Have tried on several occasions.  I know several people who do this for a living, nobody uses any kind of protection.

same here, ive never zapped anything. ive even tried. i also know several people including my brother who do this for a living and have never zapped anything and never use a grounging strap. i asked my brother about using one and he just laughed at me. Weird. hotwaterwizard must just has that "magic" touch that wizards have.

Some devices are more sensitive than others.

A regular FET is not sensitive.

MOSFET is. IRFZ40 for example is static sensitive that is why they send them in a special shielded bag.

haha, calm down dualsport. of course we are not suggesting that. that would be just plain ignorant now wouldnt it? what we are saying, is that we have never done it before. even on purpose ive never done it. ive tried. not saying it doesnt happen......saying ive never been able to do it (knock on wood).
