Typical design checks include LED drive current, required CTR range, collector-emitter voltage, output pull-up requirements, switching speed, isolation spacing, temperature conditions, and safety-standard needs. The Toshiba datasheet is the controlling reference for electrical limits, isolation ratings, package dimensions, ordering codes, and application conditions. For replacement or AVL use, confirm the complete ordering code rather than only the TLP385 family name. The D4 option is associated with safety-standard ordering requirements, while the rank and tape direction codes affect CTR classification and reel orientation. Substitutions should be reviewed for CTR rank, pinout, insulation rating, package land pattern, propagation behavior, and factory documentation status. The full-reel size is source-verified from Toshiba orderable-part data and distributor full-reel/factory-pack data showing 3,000 pieces. Buyers should still check their production feeder and approved manufacturer part number requirements before release to assembly. Applications Programmable logic controller input and output interface circuits. AC adapter and power-supply feedback or control isolation. Industrial automation modules and isolated digital interfaces. I/O interface boards that need compact surface-mount signal isolation. Microcontroller-to-field-signal isolation when design ratings match the datasheet. General-purpose isolated switching and status-sense paths. Production builds requiring full-reel SO6L photocoupler material for SMT placement. Sourcing and Documentation Notes Please review the attached Product Specification PDF before purchase or design use. The datasheet defines electrical limits, CTR rank behavior, isolation characteristics, recommended operating conditions, package drawings, safety-standard notes, and ordering information. This listing uses source-backed package and specification data from Toshiba, DigiKey, and Mouser. Confirm the exact Toshiba ordering code, tape direction, CTR rank, package marking requirements, date-code requirements, and board-level qualification status before using this component in a controlled production build. FAQ What is TLP385(D4GL-TR,E(T best suited for? It is best suited for isolated digital signal transfer where a DC-input phototransistor optocoupler is required, such as PLC interfaces, power-supply feedback paths, and general embedded I/O isolation. What isolation rating should engineers verify? Toshiba lists 5000 Vrms minimum isolation voltage for the TLP385 family. Engineers should still check the datasheet conditions, creepage, clearance, insulation category, and safety approvals required by the final product. What does the D4GL portion of the code affect? The D4 and GL code elements relate to Toshiba ordering options such as safety-standard option and CTR rank. Match the complete ordering code against the approved bill of materials before substitution. What CTR range is relevant for GL rank? Toshiba orderable-part data lists GL rank as a 100% to 200% current-transfer-ratio class. Use the datasheet test conditions when comparing CTR across optocoupler options. What output circuit does this optocoupler use? The TLP385 family uses an infrared LED input optically coupled to a phototransistor output. The output side typically needs an external collector resistor or interface circuit chosen for speed and logic threshold. What does order quantity 1 include? Order quantity 1 means one full reel containing 3,000 TLP385(D4GL-TR,E(T photocouplers. Can another TLP385 suffix replace this one? Only after checking CTR rank, safety-standard option, package, tape direction, pinout, isolation requirements, and application approval records. What design tradeoff matters most with phototransistor optocouplers? LED drive current, CTR spread, pull-up value, output capacitance, and load conditions trade off switching speed and logic margin. Validate timing and saturation behavior in the real circuit. Is it suitable for high-speed digital isolation? Use it for speeds that fit the phototransistor-output timing in the datasheet. For faster logic interfaces, compare dedicated high-speed digital isolators or logic-output optocouplers. Where can I find the datasheet? Use the attached Product Specification PDF for TLP385 electrical ratings, CTR ranks, isolation conditions, package drawings, and safety-standard notes.
