Static Discharge Issues for Zen Amp

McJerry · 25th August 2001, 01:20 PM

Hello,

The metal work is just about done on a pair of Zen monoblocks and it is about time to mount the Mosfets. I was wondering how static sensitive these devices are? What precautions should I take?

Thanks,

McJerry

You should be reasonably careful. Touch ground before you touch them. I have never popped one that i know of and i dont build amps in my socks while standing on carpet (of course i am the guy having problems with the A75). A good way to check yourself is to go for a drive and touch the door after you get out (I hate that)

My favourite method of becoming antistatic is to wash my hands. This washes away and short-circuits any static you have on them + hands are damp afterwards which further reduces risk of static.

See, your mother knew something about semiconductors!

If you can, you may short-circuit the gate and the source together, with a little croccodile wire: this is a little unconfortable, but a certain way to handle these components.

If you are concerned with reliability then wear a wrist strap and use a grounded iron and mat.Even bi-polar transistors are static sensitive.
