TVS Diode Arrays (SPA Diodes) Lightning Surge Protection- SR05 Series RoHS Pb GREEN SR05 Series 5V 25A Diode Array Description The SR05 consists of four, low capacitance steering diodes and a low voltage TVS diode that provide protection against ESD and lightning surge events. Each channel or I/O pin can safely absorb up to 25A (tp=8/20s) and repetitive ESD strikes above the maximum level (Level 4) specified in the IEC 61000-4-2 international standard without performance degradation. The low loading capacitance makes it ideal for protecting high-speed telecommunication data lines.
