Lightning Surge Protection - SP4050 Series
SP4050 Series
Description
RoHS
Pb
GREEN
The SP4050 integrates low capacitance diodes with an
additional zener diode to protect each I/O pin against ESD
and high surge events. This robust component can safely
absorb up to 20A per IEC 61000-4-5 2
nd
edition(t
p
=8/20µs)
without performance degradation and a minimum ±30kV
ESD per IEC 61000-4-2 International Standard. Their low
loading capacitance also makes them ideal for protecting
high speed signal pins.
