Multilayer Transient Voltage Surge Suppressors
ML Varistor Series
Surface Mount Varistors

www.littelfuse.com
The ML Series family of Transient Voltage Surge Suppression devices is
based on the Littelfuse Multilayer fabrication technology. These components are designed to suppress a variety of transient events, including
those specified in IEC 61000-4-2 or other standards used for Electromagnetic
Compliance (EMC). The ML Series is typically applied to protect integrated
circuits and other components at the circuit board level.
The wide operating voltage and energy range make the ML Series suitable for numerous applications on power supply, control and signal lines.
The ML Series is manufactured from semiconducting ceramics, and is
supplied in a leadless, surface mount package.The ML Series is compatible with modern reflow and wave soldering procedures.
It can operate over a wider temperature range than zener diodes, and
has a much smaller footprint than plastic-housed components.
Littelfuse Inc. manufactures other Multilayer Series products. See the
MLE Series data sheet for ESD applications, MHS Series data sheet for
high-speed ESD applications, the MLN for multiline protection and the
AUML Series for automotive applications.

Temperature De-rating
When transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times the number of pulses
per second. The power so developed must be within the specifications
shown on the Device Ratings and Specifications table for the specific
device. For applications exceeding 125oC ambient temperature, the peak
surge current and energy ratings must be derated as shown in Figure 1.
