Description
The SMX1J7.5A www.DataSheet4U.com Transil 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 85 W 10/1000 µs. The 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. The SMX1J7.5A is packaged in µQFN 2 leads.
