TVS Diode Arrays (SPA Diodes) Lightning Surge Protection- SRDA05 Series RoHS Pb GREEN SRDA05 Series 8pF 30A Diode Array Description 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=8/20s) 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.
