SP3050_11 Datasheet, PDF (1/4 Pages) Littelfuse – TVS Diode Arrays

TVS Diode Arrays (SPA^™Family of Products)
Lightning Surge Protection - SP3050 Series
SP3050 Series 6V 10A Rail Clamp Array
RoHS Pb GREEN
Description
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)
P
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.
