• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not

implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.

(1)

Refer to current limit performance application note for a discussion on relay operation during transient currents.

(2)

Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).

Notes
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering

evaluations. Typical values are for information only and are not part of the testing requirements.
