SO-8 Four Lines TVS Array for ESD Protection
Description
TVS diodes are designed to replace multilayer
varistors (MLVs) in portable applications such as
cell phones, notebook computers and PDA’s.
They offer superior electrical characteristics such
as lower clamping voltage and no device
degradation when compared to MLVs.
The SLVU2.8-4 is a TVS array designed to
protect four Uni-Directional or two Bi-Directional
lines in the common mode, or two line pairs in the
differential mode from the damaging effects of
ESD or EFT. SLVU2.8-4 is widely used in
Ethernet 10/100/1000 Base T application.
Features
* Solid-state silicon-avalanche technology
* SO-8 package
* Uni-Directional or Bi-Directional protection
* Protects up to four data lines
* 600 Watts peak pulse power (tp = 8/20µs)
* Working voltage: 2.8V
* Low clamping factor Vcl/Vbr
* Low leakage current
* Complies with the following standards:
- IEC 61000-4-2 (ESD) Air-15kv, Contact-8kv
- IEC 61000-4-4 (EFT) (5/50ns)
- IEC 61000-4-5 (Surge) (8/20μs)
