SP3050 Series

SP3050

Lightning Surge Protection - SP3050 Series

Description

Applications

The SP3050 integrates low capacitance rail-to-rail diodes

with an additional zener diode to protect each I/O pin

against ESD and high surge events. This robust device can

safely absorb surge current per IEC61000-4-5 (t

=8/20µs)

without performance degradation and a minimum ±20kV

ESD per IEC61000-4-2. Their very low loading capacitance

also makes them ideal for protecting high speed signal pins.
