Low Capacitance ESD Protection - SP3004 Series
Description
Features
Applications
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) specified 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.
• Low capacitance of
0.85pF (TYP) per I/O
• ESD protection of ±12kV
contact discharge,
±15kV air discharge,
(IEC61000-4-2)
• EFT protection,
IEC61000-4-4, 40A
(5/50ns)
• Low leakage of 1nA MAX
with V
R
=3.3V
• Small SOT563 package
saves board space
• Lightning Protection,
IEC61000-4-5, 4A
(8/20µs)
• Computer Peripherals
• Mobile Phones
• PDA’s
• Digital Cameras • Network Hardware/Ports
• Test Equipment

A single 4 channel SP300x-04
device can be used to protect
four of the data lines in a
HDMI/DVI interface. Two (2)
SP300x-04 devices provide
protection for the main data
lines. Low voltage ASIC
HDMI/DVI drivers can also be
protected with the SP300x-04,
the +V

pins on the SP300x-04
can be substituted with a
suitable bypass capacitor or in
some backdrive applications the
