The 662646-S2S3LB is a triac, SCR output optoisolator manufactured by Sharp Microelectronics.

• It falls under the category of isolators and is commonly used for electrical isolation in electronic circuits.
• The optoisolator comes in a tape and reel package with a standard package quantity of 3,000 pieces.
• It features a triac output type and operates on DC input.
• The maximum forward current (If) is 50 mA, and the typical forward voltage (Vf) is 1.2V.
• It offers an off-state voltage of 600V and can handle a maximum on-state current (It) of 50 mA.
• The optoisolator provides a voltage isolation of 3750Vrms and has a current hold (Ih) of 3.5mA.
• With its reliable performance and high voltage isolation, the 662646-S2S3LB was widely used in various electronic applications.
• Although the product is now obsolete, it served as a key component in many circuits requiring electrical isolation.
