4.4 ESD Ratings - IEC

The IEC 61000-4-2 rating consists of two measurements: contact and air. The contact rating is the maximum voltage a device can withstand from discharging an ESD pulse directly onto the device. The air-gap rating is similar, instead of discharging directly onto the device, this test involves discharging an ESD pulse over a gap of air onto the device. The higher the rating, the higher the voltage a device can withstand.

Table 4-4 breaks down the different levels to the IEC 61000-4-2 ratings. Most, if not all of TI ESD protection devices comply with the level 4 or higher rating for contact discharge, and most comply to level 4 or higher rating for air-gap discharge.

Table 4-5 shows the IEC ratings in a data sheet for an ESD protection device with a level 4 rating in both contact and air-gap discharge. The device is able to function up to the values provided in Table 4-5. For example, some ESD devices are able to function up to 30-kV contact/30-kV air-gap discharge which is greater than level 4 IEC rating.
