Description
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).
