ST SM6T22A

The SM6T Transil series are designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2 and MIL STD 883, method 3015, and electrical overstress according to IEC 61000-4-4 and 5. These devices are more generally used against surges below 600 W (10/1000 μs). The Planar technology makes it suitable for highend equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. SM6T are packaged in SMB (SMB footprint in accordance with IPC 7531 standard).
