SPLV2.8-4

Lightning Surge Protection - SPLV2.8-4 Series

Description

Features

Applications

The SPLV2.8-4 was designed to protect low voltage,

CMOS devices from ESD and lightning induced transients.

There is a compensating diode in series with each low

voltage TVS to present a low loading capacitance to the

line being protected. These robust structures can safely

absorb repetitive ESD strikes at ±30kV (contact discharge)

per IEC61000-4-2 standard and each structure can safely

dissipate up to 40A (IEC61000-4-5, t

=8/20s) with very

low clamping voltages.
