TLP2345(TPL,E

TLP2345(TPL,E is the full Toshiba ordering string for the TLP2345 high-speed photocoupler in the SO6 package (11-4L1S, five pins), verified against the maker’s datasheet ordering information (section 17, revision 6.0.A): the (TPL element is the tape type and the E element is the [[G]]/RoHS-compatible form — Toshiba writes these suffixes without a closing bracket, so the string above is the complete order code. Verified figures: input forward voltage of 1.35 V minimum, 1.55 V typical and 1.65 V maximum at 3 mA, threshold input current of 0.35 mA typical and 1.6 mA maximum, propagation delay of 120 ns maximum in each direction, pulse-width distortion of 40 ns maximum, common-mode transient immunity of ±30 kV/µs minimum, isolation voltage of 3750 Vrms minimum, a supply range of 4.5 V to 30 V, and supply current of 3 mA maximum. The selection point is a wide-supply, high-noise-immunity isolated path for gate-drive feedback and digital signals in a small 5-pin body. Selection advice: check an offer against the full (TPL,E string and the SO6 (11-4L1S) package name — the mall listing’s SO-5 wording is the same body under a generic name, and other TLP2345 suffix forms are different packing or grade codes. Parameters verified against the Toshiba TLP2345 datasheet.
