Overvoltage Suppression Fast Response VDR 25mm Zinc Oxide Varistor Resistor 25D101K 100V For Surge Protection
Description
The 25D series radial leaded varistors provides an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small discs.
The maximum peak surge current rating can reach up to 18KA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.
Features

■ Symmetrical V-1 characteristics (Non Polarity)
■ Fast responding to transient over-voltage
■ Large absorbing transient energy capability
■ Low clamping ratio and no follow-on current
■ Meets MSL level 1, per J-STD-020
■ Operating Temperature:-40 ~ +85 ℃
■ Storage Temperature:-40 ~ +125 ℃
Applications
■ Transistor, diode, IC, thyristor or triac semiconductor protection
■ Surge protection in consumer electronics
■ Surge protection in industrial electronics
■ Surge protection in electronic home appliances, gas and petroleum appliances
■ Relay and electromagnetic valve surge absorption

Current Energy and Power Dissipation Ratings
Should transients occur in rapid succession, the average times the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings and Specifications Table for the specific device. The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation.
