The TPD1E10B06-Q1 is a passive clamp that has low leakage during normal operation when the voltage between pin 1 and pin 2 is below V_RWM and activates when the voltage between pin 1 and pin 2 goes above V_BR. During IEC ESD events, transient voltages as high as ±30 kV can be clamped between the two pins. When the voltages on the protected lines fall below the trigger voltage, the device reverts back to the low leakage passive state.
