Features & Applications

The SMM4F Series 400 W 22 V Uni Directional Transient Voltage Suppressor - DO-222AA and This 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 400 W 10/1000 μs.

This planar 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 STmite flat, this minimizes PCB space consumption (footprint in accordance with IPC 7531 standard).
