TVS Diode Arrays (SPA® Diodes)
Lightning Surge Protection- SRDA3.3 Series
SRDA3.3 Series 8pF 35A Diode Array
RoHS Pb GREEN
Description
The SRDA3.3 integrates low capacitance rail-to-rail diodes
with an additional zener diode to protect I/O pins against
ESD and lightning induced surge events. This device can
safely absorb up to 35A per IEC61000-4-5 (tp=8/20μs)
without performance degradation and a minimum
±30kV ESD per IEC61000-4-2 international standard. Its
low loading capacitance makes it ideal for high-speed
interfaceprotection.
