Multiline Transient Voltage Surge Suppressor
MLN SurgeArray™Suppressor
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 “1206” 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 18VDC. SurgeArray devices
are rated to the IEC 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 filter/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.
The MLN can also be provided in a Dual version. Contact Littelfuse
for information.
