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.

• ESD protection of ±8kV

contact discharge,

±15kV air discharge,

(IEC61000-4-2)

• EFT protection,

IEC61000-4-4, 40A

(5/50ns)

• Lightning Protection,

IEC61000-4-5, 2.5A

(8/20µs)

• Low capacitance of

0.65pF (TYP) per I/O

• Low leakage current of

0.5μA (MAX) at 5V

• Complete line of small

packaging helps save

board space (SC70,

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.
