3 Description

The TPD1E10B09 device is a single-channel

electrostatic discharge (ESD) transient voltage

suppression (TVS) diode in a small 0402 package.

This ESD protection diode offers ±20 kV IEC

61000-4-2 (level 4) contact and air-gap ESD

protection. The back-to-back TVS diode configuration

allows for bipolar or bidirectional signal support.

The 10-pF line capacitance is suitable for a wide

range of applications supporting data rates up to 500

Mbps. The 0402 package is an industry standard

and is convenient for component placement in spaceconstrained

applications.

Typical applications of this ESD protection TVS diode

are circuit protection for audio lines (microphone,

earphone, and speaker phone), SD interfacing,

keypad or other buttons, VBUS pin and ID pin of

USB ports, and general-purpose I/O ports. This ESD

clamp is good for the protection of end equipment

like eBooks, tablets, remote controllers, wearables,

set-top boxes, and electronic point of sale equipment.
