Description

The SMM4F Transil serie 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). Transil is a trademark of

STMicroelectronics.
