Description
The SMX1J 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 SMX1J is packaged in µQFN-2L.
