Lightning Surge Protection- SRDA05 Series
Description
Applications
The SRDA05 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 robust device
can safely absorb up to 30A 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 interface
protection.
