Hi,
my circuit has some BSS127 nMOS class 0 (<250V --> JESD22-A114-HBM) ; if, when it is not powered, drain only was exposed to an ESD, with gate and source floating (less than a certain capacity to ground), how many chances I have to save the mosfet, maybe deflecting the discharge through spark gaps dimensioned for 1kV ESD?
