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.
