- Part of the SRDA3.3-4BTG comparator family.
TVS Diode Arrays (SPA® Diodes)
Lightning Surge Protection- SRDA3.3 Series
SRDA3.3 Series 8p F 35A Diode Array
Ro HS 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 ±30k V ESD per IEC61000-4-2 international standard. Its low loading capacitance makes it ideal for high-speed interfaceprotection.
