Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.

1. TVS devices are normally selected according to the working peak reverse voltage (VRWM), which should be equal or greater than the DC

or continuous peak operating voltage level.

2. VBR is measured at pulse test current IT.
