Thanks in advance.
nschutten said:Hi ESDSolutions,
I was wondering about the following: when reading about ESD, it is usually about protecting the gate of the transistor. But how about the drain/source connections (e.g. the connections of a power switching transistor)? Wouldn't the voltage at the drain/source connections go to the channel, which then (assuming the gate voltage is not affected by ESD) would result in the same effect (with only sign reversal) as when the gate would have the ESD event and the drain/source unaffected?
Many thanks in advance to anyone who can help clarify this for me!

I am also doing some ESD study and have some few questions on ggnmos cell.
How is the holding voltage of ggnmos set? Is it process dependent?
What happens to the N+/PW junction after avalanche breakdown? Does it act like a zener diode?
Thanks in advance.

nschutten said:Thanks, prcken, for helping me by giving some further info regarding my ESD question.
BTW: the transistor in question is not a power down transistor, it is a switching transistor for a DC/DC converter; so the source and drains need to be connected directly to the pads (no series components etc. can be used, since these only introduce losses). Since the PN junctions are very large, do you think this kind of device will be self-protecting?
pbs681 said:hi all,
have a basic question here. I am studying one IO pad design, NMOS and PMOS driver is used as an ESD device. But, I don't know why only NMOS driver has ballast resistor (nwell res). Why PMOS driver doesnt have it. Appreciate ur help!
