10D Series Metal-Oxide Varistor
Features
Wide range of operating voltages from 5 Vrms to 1000 Vrms (6 Vdc to 1465 Vdc) Fast response time of less than 25ns, instantly clamping of transient over-voltage Capable to handle high surge current High energy protection capability Low clamping voltages for efficient surge behavior Low capacitance values, ideal for digital switching circuit protection High insulation resistance, preventing electric arcing to adjacent components or
circuits
Application
Transistors, diodes, integrated circuits (IC), thyristors or Triac semiconductor protection Surge protection for consumer electronics Surge protection for industrial appliances Surge protection for electronic home appliances, gas or petroleum operated appliances Relay and electromagnetic surge absorption.
