Description

The Si85xx products are unidirectional ac current sensors available in fullscale ranges of 5, 10, and 20 A. Si85xx products are ideal upgrades for older current-sensing technologies offering size, performance and cost advantages over current transformers, Hall effect devices, DCR circuits and other approaches. The Si85xx are extremely low loss, adding less than 1.3 m of series resistance and less than 2 nH series inductance in the sensing path at 25 ºC. Current-sensing terminals are isolated from the other package pins to a maximum voltage of 1,000 VDC.
