ZV Series — Low Voltage Leaded Varistors
Description
The ZV Series of low voltage leaded multilayer varistors (MLVs) is designed to protect
sensitive electronics devices operating in the low voltage region against high voltage / current
surges. They offer excellent transient energy absorption due to improved energy volume
distribution and power dissipation. Low voltage MLVs cover a wide DC operating voltage
range from 3 to 56V.
Features
• AC operating voltage (Vrms) from 2V to 40V
• DC operating voltage (Vdc) from 3V to 56V
• 5 model sizes available 05, 07, 10, 10, 14, 20
• Available with straight or crimped leads
• Broad range of current and energy handling capabilities
• +125°C continuous operating temperature
• Dimensional and weight savings on PC board
• Bi-directional, lower clamping voltages than disc type
varistors
Applications
• Suppression of inductive switching or other transient
events at the circuit board level
• Provides on-board transient voltage protection for ICs
and transistors
• Used to help achieve electromagnetic compliance of
end products
• Replace larger TVS Zener diodes in may applications
