EL357N(B)(TA)-G

EL357N(B)(TA)-G is the full ordering string for the Everlight EL357N transistor-output optocoupler in SOP-4, with every element of the string verified against the maker’s datasheet ordering composition (revision 9, status Approved): the (B) is the current-transfer-ratio rank, (TA) is the tape-and-reel packing at 3,500 pieces per reel, and the -G suffix is the halogen-free form; this string carries no VDE option. Verified figures for the B rank: a current transfer ratio of 130 % to 260 %, input forward voltage of 1.2 V typical and 1.4 V maximum, collector-emitter breakdown of 80 V minimum, and isolation voltage of 3750 Vrms. The selection point is guaranteed rank banding in a surface-mount 4-pin body for isolated feedback and signal paths. Selection advice: the rank is the specification — an offer of a different EL357N rank, or of the unranked base type, changes the gain of an isolated loop and must be requalified; keep the full string, packing code included, in your RFQ. Parameters verified against the Everlight EL357N datasheet, revision 9.
