Description
The MLN SurgeArray™ Suppressor is designed to
help protect components from transient voltages that
exist at the circuit board level. This device provides four
independent suppressors in a single leadless chip in order
to reduce part count and placement time as well as save
space on printed circuit boards.
SurgeArray™ devices are intended to suppress ESD, EFT
and other transients in order to protect integrated circuits
or other sensitive components operating at any voltage
up to 18V
. SurgeArray™ devices are rated to the IEC
DC
61000-4-2 human body model ESD to help products attain
EMC compliance. The array offers excellent isolation and
low crosstalk between sections.
The inherent capacitance of the SurgeArray™ Suppressor
permits it to function as a fi lter/suppressor, thereby
replacing separate Zener/capacitor combinations.
The MLN array is manufactured using the Littelfuse
Multilayer technology process and is similar to the
Littelfuse ML and MLE Series of discrete leadless chips.
