TVS Diode Arrays (SPA^® Diodes)
Lightning Surge Protection - SP3051 Series
SP3051 Series 6V 20A Diode Array
RoHS Pb GREEN
Description
The SP3051 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 20A of current per IEC61000-4-5 (t_P=8/20µs)
without performance degradation and a minimum ±30kV
ESD per IEC61000-4-2. Their very low loading capacitance
also makes them ideal for protecting high speed signal pins.
