The SMM4F Transil 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).Typical peak pulse power: 400 W (10/1000 µs) 2.4 kW (8/20 µs)Stand off voltage range: from 5 V to 33 VUnidirectional typesLow leakage current: 0.2 µA at 25 °C 1 µA at 85 °COperating Tjmax: 175 °CJEDEC registered package outlineRoHS packageHalogen free molding compoundComplies with the following standards IEC 61000-4-2 level 4:15 kV (air discharge)8 kV (contact discharge)MIL STD 883G-Method 3015-7: class325 kV (human body model)
