Clamping voltage is the amount of voltage a system is exposed to during a transient event and measures how well an ESD diode protects the downstream system circuitry. The clamping voltage is one of the most important specs for an ESD protection device and can be determined from the Transmission Line Pulse (TLP) plot, mentioned in the next section, if not in the data sheet. Table 4-10 shows the comparison between an IEC strike and the TLP current. For most ESD devices, the clamping voltage is specified at 16-A/8-kV IEC.
IEC ESD | TLP Current |
---|---|
2 kV | 4 A |
4 kV | 8 A |
6 kV | 12 A |
8 kV | 16 A |
