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. The “E” series is a family of low capacitance parts, specifically
designed for ESD protection of high data rate applications.
BENEFITS
• Minimal signal distortion
• Help to protect sensitive equipment against typical ESD events
• 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
• Low capacitance
• 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 Complaint
APPLICATIONS SYMBOL
ESD protection of:
• High speed computer I/O ports and interfaces (USB, IEEE 1394, etc…)
• Portable devices
• Telecom equipment
MATERIALS INFORMATION
ROHS Compliant ELV Compliant
