Low Capacitance ESD Protection Array
RoHS Pb GREEN SP3004 Lead-Free/Green Series
Description
The SP3004 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 (Level 4) speciï¬ed in the
IEC 61000-4-2 international standard 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.
