20D471K Datasheet PDF - UN Semiconducctor INC

Description
The 20D 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 10KA (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 voltage (V1mA) range from 8V to 1800V
◆ Fast responding to transient over-voltage
◆ Large absorbing transient energy capability
◆ Low clamping ratio and no following-on current
◆ Meets MSL level 1, per J-STD-020

Applicable
◆ 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
