The SMF Series has been designed to protect sensitive equipment against electro-static discharges according to IEC 61000-4-2, MIL STD 883 method 3015, and electrical over stress such as IEC 61000-4-4 and 5. They are generally for surges below 200-W (10/1000-μs). This technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. Their low clamping voltages provide a better safety margin to protect sensitive circuits with extended life time expectancy. packaged in SOD123FL, This minimizes PCB space consumption.
