MOC3083S-TA1 SMD IC -6P Lite-On Opto isolators coupler 3083 MOC3083S-TA1

Product Overview:

A surface-mount, 6-pin zero-cross triac driver optoisolator (photocoupler) integrated circuit designed for isolated AC power control. It provides high galvanic isolation between low-voltage logic control circuits and high-voltage AC power loops, utilizing an internal zero-voltage crossing bilateral switch to reduce current inrush and minimize electromagnetic interference (EMI) during AC load switching.
