VDE Varistor 820V Zinc Oxide Metal Voltage Dependent Resistor VDR 25D821K 821k D25 0

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 20KA (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:

Wide operating voltages ranging from 60Vac to 750Vac (85Vdc to 990Vdc).
Fast response time of less than 25ns, instantly clamping the transient over voltage.
High surge current handling capability.
High energy absorption capability.
Low clamping voltages, providing better surge protection.
Low capacitance values, providing digital switching circuitry protection.
High insulation resistance, preventing electric arching to the adjacent devices or circuits.

Applications:

u Transistor, diode, IC, thyristor or triac semiconductor protection

u Surge protection in consumer electronics

u Surge protection in industrial electronics

u Surge protection in electronic home appliances, gas and petroleum appliances

u Relay and electromagnetic valve surge absorption
