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 space-constrained 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, V BUS 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.
