The Si86S6x products are state-of-the-art digital isolators that include several outstanding and unique features. These devices are robust, with a 6.0 kVrms isolation barrier, and have low-power and sleep modes for conserving power.


Isolators are switches used in electrical systems to confirm that a circuit is fully discharged before it is handled. Consider a high voltage situation that is part of the electrical grid that transmits electricity from the power plant to the home. The high voltage that passes through the system is always a concern and sometimes, even though it has been disconnected from the source, it can still maintain a residual charge. The residual charge can be fatal if not discharged and that is what the isolators do, they discharge the system when it needs to be worked on.

In commercial applications there are smaller isolators used to protect the home from lighting. These lightning isolators are also a way to discharge the electricity that has been transmitted by the lighting, and it isolates the charge to the ground so that it does not linger in the conductor that it first passed through. Isolators are a very useful tool when it comes to discharging voltage. There are also minute isolators for equipment that is faulty.

Discharging a charged item is as simple, in theory, as connecting the item to the ground where the charge is then allowed to flow to the earth. This is the fastest and safest way to transfer excess charge out of a system. In the electronics industry, it is also customary to discharge the equipment and machinery with isolators. These isolators are smaller in size and are placed directly in the circuit board. Their functions; however, are identical to the larger ones used at a power plant.
