EL3H7(B)(TA)-G

EL3H7(B)(TA)-G is the full ordering string for the Everlight EL3H7 transistor-output optocoupler in the 4-pin SSOP body, with every element of the string verified against the maker’s datasheet ordering composition (EL3H7-G series, revision 11, released November 2024): the (B) is the current-transfer-ratio rank, (TA) is the tape-and-reel packing at 6,000 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 % at 5 mA input current and 5 V collector-emitter voltage, 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 guaranteed rank banding in a low-profile 4-pin body for isolated feedback and signal paths. Selection advice: the rank is the specification — this catalog also lists the EL3H7(C)(TA)-G C-rank sibling from the same maker and an EL3H7C from AOTE, a different maker’s series under the same designation; ranks and makers are separate order codes, and a substitution changes the gain of an isolated loop and must be requalified, not treated as a drop-in. Parameters verified against the Everlight EL3H7-G series datasheet, revision 11.
