HOW SURGE EVENTS HAPPEN In a normal equipment environment there are reasonable threats from Electrostatic Discharge (ESD) and lightning transients which can cause loss of data integrity and permanent damage to equipment if not controlled. ESD threats are generated by personnel movement. which causes triboelectric (rubbing causing a separation of charge) charges to accumulate on equipment or clothing and then be discharged through hand or tool "touch". This discharge can represent several thousand volts at 10 to 30 amps of current. There are two primary threats from an ESD event. These are the peak current of the discharge and the resulting electromagnetic field. Should the input to the device not be protected from this ESD threat. as little as 100 milli-Joules can cause permanent failure to an input device at the silicon die level. Lightning also can create a large disturbance and delivery destructive energy to the equipment. These lightning events cause differential voltages to develo
