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).

1. Pulse test: tp <50ms.
2. To calculate maximum clamping voltage at other surge currents, use the following formula VCLmax = RD x IPP + VBRmax
3. To calculate VBR versus junction temperature, use the following formula: VBR @ Tj = VBR @ 25 °C x (1 + αT x (Tj - 25))
