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 SP3003-04 device can be used to
protect four (4) of the data lines in a HDMI/DVI interface
so two (2) SP3003-04 devices provide protection for all
eight (8)TMDS lines.
