7 Detailed Description
7.1 Overview
The TPD2E007 an ESD protection device designed to offer system level ESD solutions for wide range of
portable and industrial applications. The back-to-back diode array allows AC-coupled or negative-going data
transmission (audio interface, LVDS, RS-485, RS-232, etc.) without compromising signal integrity. The PicoStar
package is intended to be embedded inside the printed circuit board which saves board space in portable
applications. This device exceeds the IEC 61000-4-2 (Level 4) ESD protection and is ideal for providing system
level ESD protection for the internal ICs when placed near the connector.

7.3 Feature Description
The TPD2E007 an ESD protection device designed to offer system level ESD solutions for wide range of
portable and industrial applications. The back-to-back diode array allows AC-coupled or negative-going data
transmission (audio interface, LVDS, RS-485, RS-232, etc.) without compromising signal integrity. The PicoStar

level ESD protection for the internal ICs when placed near the connector.
7.3.1 IEC 61000-4-2 Level 4 ESD Protection
The I/O pins can withstand ESD events up to ±12-kV contact and ±15 kV-air. An ESD/surge clamp diverts the
current to ground.
7.3.2 IEC 61000-4-5 Surge Protection
The I/O pins can withstand surge events up to 4.5 A (8/20 µs waveform). An ESD/surge clamp diverts this
current to ground.
7.3.3 IO Capacitance
The capacitance between each I/O pin to ground is 15 pF.
7.3.4 Low 50-nA Leakage Current
The I/O pins feature a low 50-nA (max) leakage current.
7.3.5 Space-Saving PicoStar and SOT Package
This device is offered in both a space-saving PicoStar package, as well as a standard DCK package.
7.4 Device Functional Modes
TPD2E007 is a passive integrated circuit that triggers when voltages are above or below V
BR
. During ESD
events, voltages as high as ±15 kV (air) can be directed to ground via the internal diode network. Once the
voltages on the protected line fall below the trigger levels of TPD2E007 (usually within 10’s of nano-seconds) the
device reverts to passive.
