Lightning Surge Protection- SR70 Series

Description

Features

Applications

The SR70 consists of four, low capacitance, rail-to-rail

diodes that provide protection against ESD and lightning

surge events.These robust diodes can safely absorb up to

40A (t

=8/20μs) and repetitive ESD strikes at the maximum

level (Level 4) speciﬁed in the IEC 61000-4-2 international

standard without performance degradation.

Its low loading capacitance makes it ideal for protecting

high-speed data lines such as VDSL and VDSL2.
