## **Complies with the following standards** - IEC 61000-4-2 level 4: - 15 kV (air discharge) - 8 kV (contact discharge) - MIL STD 883G-Method 3015-7: class3B - 25 kV (human body model) ## **Description** The SMA6F 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 600 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 provides a better safety margin to protect sensitive circuits with extended life time expectancy. Packaged in SMAflat non exposed pad, this minimizes PCB space consumption (footprint in accordance with IPC 7531 standard).
