PRODUCTION DATA.
The TPD4E001 is a passive-integrated circuit that activates whenever voltages above VBR or below the lower diodes Vforward (–0.6 V) are present upon the circuit being protected. During ESD events, voltages as high as ±15 kV can be directed to ground and VCC via the internal diode network. Once the voltages on the protected lines fall below the trigger voltage of the TPD4E001 (usually within 10s of nano-seconds) the device reverts back to a high-impedance state.
