LITEON

LITEON is the catalog name for Lite-On Technology’s optoelectronics line, and the profiles here cover its transistor-output optocouplers — the isolated feedback and signal-transfer workhorses of power supplies, industrial controls and appliance interfaces. Three codes anchor the hub. The LTV-217-B-G is a SOP-4 coupler whose B rank guarantees a current transfer ratio of 130 % to 260 %, with the -G suffix marking the halogen-free form. The LTV-817S-TA1-C brings the long-running 817 family in surface-mount reel packing (the TA1 code), C-ranked at 200 % to 400 % with 5,000 Vrms isolation. The LTV-357T-C is the miniflat member, again C-ranked at 200 % to 400 %, with 3,750 Vrms isolation. Across this line the rank letter is part of the specification: an unranked or differently ranked offer is a different component for design purposes even when the package matches.

Sourcing notes for LITEON parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
