Technical Specifications

The ZNRV10751U typically exhibits a varistor voltage in the vicinity of 750V. The maximum surge current rating is a critical parameter and is dependent on the specific surge waveform and the number of applied surges; therefore, it is essential to consult the official Panasonic datasheet for accurate values. The clamping voltage determines the voltage level to which the transient voltage is limited. It is commonly available in a disc-shaped package with radial leads for easy mounting on printed circuit boards (PCBs). Energy absorption capability defines how much energy the varistor can absorb before failure.

It is crucial to always consult the official Panasonic datasheet for detailed electrical characteristics, surge current ratings, derating curves, safety information, and recommended application guidelines before utilizing the ZNRV10751U in any electronic circuit design.
