ZV Series — Low Voltage SMD Varistors
Description
The ZV Series of low voltage varistors is designed to protect sensitive electronics devices
against high voltage surges in the low voltage region. They offer excellent transient energy
absorption due to improved energy volume distribution and power dissipation. Low voltage
varistors cover wide DC operating voltage range from 3V to 125V.
ZV varistors are typically applied to protect integrated circuits and other components at the
circuit board level
Features
• AC operating voltage (Vrms) from 2V to 95V
• DC operating voltage (Vdc) from 3V to 125V
• No plastic coating guarantees better flammability rating
• Bi-directional, low clamping voltages
• Broad range of current and energy handling capabilities
• +125°C continuous operating temperature
• Dimensional and weight savings on PC board
• AgPd end terminations
Applications
• ESD protection for components sensitive to IEC 1000-4-2,
MIL-STD 883C Method 3015.7 and other industry specifications
• Suppression of inductive switching or other low to medium transient
events at the circuit board level
• Provides on-board transient voltage protection of ICs and transistors
• Replace larger surface mount TVS Zeners in many applications
• Used to help achieve electromagnetic compliance of end products
• 6 model sizes available 0603, 0805, 1206, 1210, 1812, and 2220
