VRMS

(1)

Apply creepage and clearance requirements according to the specific equipment isolation standards of an application. Care must be

taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the

printed circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques

such as inserting grooves, ribs, or both on a PCB are used to help increase these specifications.

(2)

This device is suitable for safe electrical insulation only within the safety ratings. Compliance with the safety ratings shall be ensured

by means of suitable protective circuits.

(3)

Testing is carried out in air to determine the surge immunity of the package.

(4)

Testing is carried in oil to determine the intrinsic surge immunity of the isolation barrier.

(5)

Apparent charge is electrical discharge caused by a partial discharge (pd).

(6)

All pins on each side of the barrier are tied together, creating a two-pin device.

(7)

Either method b1 or b2 is used in production.
