MLN Series - Multiline Transient Voltage Surge Suppressor

The MLN Surge Array 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.

Surge Array 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 DC. Surge Array devices are rated to the IEC 6100-4-2 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 Surge Array 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-line version. Contact Littelfuse for information.
