SPA™ Silicon Protection Array Products
Low Capacitance ESD Protection Array
HF ^{RoHS Pb GREEN} SP3001 Lead-Free/Green Series
Description
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.
