Description

The Si85xx products are unidirectional ac current sensors available in full-scale

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 °C. Current-sensing terminals are

isolated from the other package pins, providing up to 5 kV

safety approval ratings.

Safety Approval (20-Pin SOIC Only)
