Low Capacitance ESD Protection - SP0504S Series
SP0504S Series 0.85pF Diode Array
Pinout
Pb
Description
The SP0504S 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.
Features
• Low capacitance of
0.85 pF (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 current of
0.5μA (MAX) at 5V
• Small packaging options
saves board space
• Lightning Protection,
IEC61000-4-5, 4.5A
(8/20µs)

A single 4 channel SP0504S device can be used to protect
four of the data lines in a HDMI/DVI interface. Two (2)
SP0504S devices provide protection for the main data lines.
Low voltage ASIC HDMI/DVI drivers can also be protected
with the SP0504S, the +V
pins on the SP0504S can be

substituted with a suitable bypass capacitor or in some
backdrive applications the +V
