LTV-817S-TA1-C

LTV-817S-TA1-C is a transistor-output optocoupler from LITEON in a surface-mount 4-pin package, with the ordering code verified piece by piece against the maker’s documentation: S is the surface-mount form, TA1 is the tape-and-reel packing, and C is the current-transfer-ratio rank. Verified figures for the C rank: a current transfer ratio of 200 % to 400 %, input forward voltage of 1.2 V typical and 1.4 V maximum, collector-emitter breakdown of 35 V minimum, and isolation voltage of 5000 Vrms. The selection point is the combination this code assembles — a high transfer rank of the 817 family, reel packing for pick-and-place lines, and a 5 kVrms isolation rating in a compact SMD body, for isolated feedback and logic interfaces. Selection advice: the rank letter is part of the specification — a B-rank or unranked 817 offer does not carry this code’s 200 % minimum transfer ratio — so match the full LTV-817S-TA1-C string, packing included, when approving a substitute. Parameters verified against the LITEON LTV-817 documentation (C-rank row).
