3 Description

The TPD4E101 device is a four-channel electrostatic discharge (ESD) transient voltage suppression (TVS) diode array in an ultra small 0.8-mm × 0.8-mm package. This TVS protection device offers ±15-kV contact ESD, ±15-kV IEC air-gap protection, and has four back-to-back TVS diodes for bipolar or bidirectional signal support. The 4.8-pF typical line capacitance of this ESD protection diode array is suitable for a wide range of applications supporting data rates up to 700 Mbps. The DPW package is convenient for component placement in space-constrained applications and the 0.48-mm pitch helps save on PCB manufacturing costs.

Typical applications of this ESD protection device are circuit protection for SIM cards, audio lines (microphones, earphones, and speakerphones), SD interfaces and pushbuttons. This ESD clamp is good for providing protection in end-equipment like cell phones, portable media players, wearables, set-top boxes, and eBooks.
