Introduction

 
Multilayer chip varistors(MLV) have good nonlinear voltage-current characteristics and high surge capability. They also have fast- response characteristics in several hundred pico second level. They are very suitable
and widely used for the problems of transient over-voltage protection caused by ESD(Electrostatic Discharge).
 
Features
 
• The fastest response time about 300~700ps
• Repetitive pulse characteristics
• High discharge transient current and energy handling capability
• Thermal stability through 125Ç
• EMI/RFI Attenuation characteristics
 
 

Applications

• Latch up protection for CMOS
• MOSFET protection for ESD/EOS
• High speed data I/O Port protection
• Keypad, Keyboard protection
• CDMA, GSM, Cordless phone		 • Notebook, Workstations
• Digital camcorder
• CD-ROM, DVD-ROM, MD, MP3-PLAYER
• Automotive Application
• Onboard computer, electric motor control
