Surface Mount Device
Description
Cooper Bussmann®MLVA Series of multilayer varistors are designed to pro-
tect electronic circuits from ESD damage. With its small, standardized 0201,
0402 and 0603 sizes, it’s easy to implement them into any circuit board
design. The MLVA is suitable for push button, power line and low frequency
overvoltage protection.
Features
Zinc oxide based ceramic chip
Provides ESD protection with fast response time (<1ns) allowing
equipment to pass IEC 61000-4-2 Level 4 Test
0402 and 0603 meet IEC 61000-4-4 and 61000-4-5
Low profile designs for board space savings
Low and stable leakage current reduces power consumption
Low clamping voltage
Wide 5.5 to 26Vdc operating voltage range
Halogen free and RoHS compliant for global applications

Working Voltage Vrms - Maximum AC operating voltage the varistor can maintain and not exceed 10μA leakage current for 0402, 0603.
Working Voltage Vdc - Maximum DC operating voltage the varistor can maintain and not exceed 10μA leakage current for 0402, 0603.
Varistor Voltage - Voltage across the device measured at 1mA DC current. Equivalent to VB, “breakdown voltage.”
Clamping Voltage - Maximum peak voltage across the varistor with 8/20μs waveform and 1A pulse current.
Capacitance - Device capacitance measured with zero volt bias 1Vrms at 1MHz.
Peak Current - Maximum peak current which may be applied with 8/20μs waveform without device failure.
Transient Energy - Maximum energy which may be dissipated with the 10/1000μs waveform without device failure.
