7 Detailed Description
7.1 Overview
The TPD2E001 is a two-channel Transient Voltage Suppressor (TVS) based Electrostatic Discharge (ESD)
protection diode array. The TPD2E001 is rated to dissipate ESD strikes at the maximum level specified in the
IEC 61000-4-2 Level 4 international standard.

7.3 Feature Description
TPD2E001 is a uni-directional Electrostatic Discharge (ESD) protection device with low capacitance. The device
is constructed with a central ESD clamp that features two hiding diodes per line to reduce the capacitive loading.
This central ESD clamp is also connected to V
CC
to provide protection for the V
CC
line. Each IO line is rated to
dissipate ESD strikes above the maximum level specified in the IEC 61000-4-2 level 4 international standard.
The TPD2E001's low loading capacitance makes it ideal for protection high-speed signal terminals.
7.4 Device Functional Modes
TPD2E001 is a passive integrated circuit that activates whenever voltages above V
BR
or below the lower diodes
V
forward
(–0.6V) are present upon the circuit being protected. During ESD events, voltages as high as ±15 kV can
be directed to ground and V
CC
via the internal diode network. Once the voltages on the protected lines fall below
the trigger voltage of the TPD2E001 (usually within 10's of nano-seconds) the device reverts back to a high
impedance state.
