GENERAL DESCRIPTION
These Multi Layer Varistors are small, leadless, surface mount packages made of multiple layers of Zinc Oxide, with
electrodes between them. They are used to help protect integrated circuits and other sensitive equipment. Their
small size is ideal for high density printed circuit boards.
BENEFITS
• Help to protect sensitive equipment against typical ESD, EMC and EOS (Electrical Over Stress) events
and transients
• Cost efficient assembly and protection
• Resistance to standard wave solder fluxes, provides excellent solderability
• Space savings
• Longer battery life due to low leakage current
FEATURES
• Bidirectional clamping
• Compatible with standard surface mount methods
• Low and stable leakage current
• Low clamping voltage
• Quick response time (<1ns)
• High transient current capability
• RoHS Compliant
APPLICATIONS SYMBOL
ESD, EMC and EOS protection of:
• Computer I/O ports and interfaces (USB, IEEE 1394, etc…)
• Portable devices
• Automotive electronic circuits
• Telecom equipment
• Medical instruments
