Notes
• 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 wave profile for soldering conditions for through hole devices
(2) Total power dissipation value is based on 2S2P PCB. Refer to power phototriac application note for PCB design tips
