TVS Diode Arrays (SPA^™Family of Products)
Low Capacitance ESD Protection - SP3003 Series
SP3003 Series 0.65pF Rail Clamp Array
RoHS Pb GREEN
Description
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.

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.
