Low Capacitance ESD Protection - SP3001 Series
Description
Features
Applications
The SP3001 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.
• Low capacitance of
0.65pF (TYP) per I/O
• ESD protection of ±8kV
contact discharge, ±15kV
air discharge,
(IEC61000-4-2)
• EFT protection,
IEC61000-4-4,
40A (5/50ns)
• Low leakage current of
0.5μA (MAX) at 5V
• Small SC70 ( JEDEC MO-
203) package saves board
space
• Lightning Protection,
IEC61000-4-5, 2.5A
(8/20µs)
• Computer Peripherals
• Mobile Phones
• PDA’s
• Digital Cameras • Network Hardware/Ports

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
+V
CC
of the SP300x-04 can be
floated or NC.
