7 Detailed Description

7.1 Overview

The TPD1E10B06 is a single-channel ESD TVS diode in a small 0402 package. This TVS protection product

offers ±30-kV IEC air-gap, ±30-kV contact ESD protection, and has an ESD clamp circuit with a back-to-back

TVS diode for bipolar or bidirectional signal support. The 12-pF line capacitance of this ESD protection diode

is suitable for a wide range of applications supporting data rates up to 400 Mbps. The 0402 package is an

industry standard and is convenient for component placement in space-saving applications.

Typical application of this ESD protection product is the circuit protection for audio lines (microphone,

earphone, and speakerphone), SD interfacing, keypad or other buttons, VBUS pin and ID pin of USB ports,

and general-purpose I/O ports. This ESD clamp is a good fit for the protection of the end equipment like

ebooks, tablets, remote controllers, wearables, set-top boxes, and electronic point of sale equipment.

7.3 Feature Description

TPD1E10B06 is a bidirectional TVS with high ESD protection level. This device protects circuit from ESD strikes

up to ±30-kV contact and ±30-kV air-gap specified in the IEC 61000-4-2 level 4 international standard. The

device can also handle up to 6-A surge current (IEC61000-4-5 8/20µs). The I/O capacitance of 12 pF supports a

data rate up to 400 Mbps. This clamping device has a small dynamic resistance of 0.4

Ω typically, which makes

the clamping voltage low when the device is actively protecting other circuits. For example, the clamping voltage

is only 10 V when the device is taking 1-A transient current. The breakdown is bidirectional so that this protection

device is a good fit for GPIO and especially audio lines which carry bidirectional signals. Low leakage allows the

makes this ESD device work at extensive temperatures in most environments. The space-saving 0402 package

can fit into small electronic devices like mobile equipment and wearables.

7.4 Device Functional Modes

TPD1E10B06 is a passive clamp that has low leakage during normal operation when the voltage between pin 1

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.
