SP3003 Series

Low Capacitance ESD Protection - SP3003 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.

A single 4 channel SP300x-04

device can be used to protect

four of the data lines in a

HDMI/DVI interface. Two (2)
