TVS Diode Arrays (SPA^™Family of Products)
Low Capacitance ESD Protection - SP3002 Series
SP3002 Series 0.85pF Rail Clamp Array
RoHS Pb GREEN
Description
The SP3002 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.

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_CC pins on the SP300x-04
can be substituted with a
suitable bypass capacitor or in
some backdrive applications the
+V of the SP300x-04 can be
CC
floated or NC.
