LTV-354T-A

LTV-354T-A is the A-rank ordering form of the LITEON LTV-354T transistor-output optocoupler in the SOP-4 mini-flat body (2.0 mm profile), verified against the maker’s rank table (document BNS-OD-C131/A4): the A rank mark guarantees a current transfer ratio of 50 % to 150 % at 1 mA input current and 5 V collector-emitter voltage. That rank row is this code’s specification — the family’s wider 20 % to 400 % span belongs to the unranked or differently ranked ordering basis and is not claimed here. Further verified figures: input forward voltage of 1.2 V typical and 1.4 V maximum, collector-emitter breakdown of 35 V minimum, collector-emitter saturation voltage of 0.1 V typical and 0.2 V maximum, collector dark current of 100 nA maximum, isolation resistance in the 5×10¹⁰ Ω to 1×10¹¹ Ω range, response times of 4 µs typical and 18 µs maximum, and isolation voltage of 3750 Vrms. The selection point is a guaranteed, modest transfer band in a low-profile 4-pin body for isolated feedback in adapters and appliance controls. Selection advice: ranks are separate order codes — an offer of the unranked base type does not guarantee the 50 % floor this A rank carries; keep the full LTV-354T-A string in your RFQ. Parameters verified against the LITEON LTV-354T documentation.
