Low Capacitance ESD Protection Array

SP3003 Lead-Free/Green Series

Description

Features

Applications

The SP3003 has ultra low capacitance rail-to-rail diodes

with an additional zener diode fabricated in a proprietary

silicon avalanche technology to protect each I/O pin

providing a high level of protection for electronic equipment

that may experience destructive electrostatic discharges

(ESD). These robust diodes can safely absorb repetitive

ESD strikes at the maximum level specified in the IEC

61000-4-2 international standard (Level 4, ±8kV contact

discharge) without performance degradation. Their very low

loading capacitance also makes them ideal for protecting

high speed signal pins such as HDMI, DVI, USB2.0, and

IEEE 1394.
