EL3H7C

EL3H7C is the C-rank ordering variant of the AOTE (Taiwan AOTE Semiconductor) EL3H7X transistor-output optocoupler in SSOP-4, verified against the maker’s own EL3H7X specification (released November 2022): the X in the family name is the rank position, the ranks run A, B, C, D or unranked, and this code carries the C rank. Verified figures are AOTE’s own C-rank row: a current transfer ratio of 200 % to 400 % at 5 mA input current and 5 V collector-emitter voltage (the family spans 80 % to 600 % across its ranks), input forward voltage of 1.2 V typical and 1.4 V maximum, collector-emitter saturation voltage of 0.1 V typical and 0.2 V maximum at 10 mA input and 1 mA collector current, collector-emitter breakdown of 80 V minimum, collector dark current of 100 nA maximum, isolation voltage of 3750 Vrms, and an operating range of −55 °C to +110 °C. The selection point is a guaranteed 200 % to 400 % transfer band in a low-profile 4-pin body for isolated feedback and signal paths. Selection advice: the EL3H7 designation is also used by Everlight for its own SSOP-4 series, listed separately in this catalog in B-rank and C-rank ordering strings; the two makers’ tables are not interchangeable — the attribution is part of the specification, so state the maker and the full EL3H7C string in your RFQ. Parameters verified against the AOTE EL3H7X specification.
