Its current transfer ratio spans 900% minimum to 8000% maximum at an LED forward current of 500 µA — a 9:1 spread that accommodates LED drive current variation across temperature and aging without losing logic-level output. The Darlington stage delivers up to 80 mA continuous output current at a maximum collector-emitter voltage of 18 V, making it suitable for driving PLC digital inputs, small relays, or DC loads directly from the optocoupler output. ## Isolation and switching performance Rated for 5000 Vrms isolation, the TLP2703 meets the reinforced insulation requirement for mains-connected industrial interfaces per IEC 60950-1 and IEC 62368-1. The 6-SO wide-body package with 0.295-inch (7.50 mm) body width provides the physical creepage distance needed to sustain that voltage rating across the isolation barrier. Switching times are specified as 330 ns typical turn-on and 2.5 µs typical turn-off — fast enough for 100 kHz digital signal isolation or low-speed PWM, but not intended for high-speed data links. The 1.47 V typical forward voltage at 20 mA maximum LED current keeps the input-side power dissipation low. ## Temperature grade and supply posture Operating temperature spans -40°C to 125°C, covering industrial automation, motor-drive feedback, and under-hood automotive environments without derating. Supplied in Tape & Reel (TR) or Cut Tape (CT) options for surface-mount assembly. The 6-SO package footprint is common across Toshiba's optocoupler family, simplifying board layout if a different channel count or output configuration is later required.","metaTitle":"TLP2703(TP,E – Toshiba Darlington Optocoupler, 5000Vrms","metaDescription":"Toshiba TLP2703(TP,E Darlington optocoupler: 900%–8000% CTR at 500µA, 5000Vrms isolation, 80mA output, -40°C to 125°C.

This wide range is typical for Darlington optocouplers and means the output can sink a load current between 4.5 mA and 40 mA at the test condition — design the input drive and pull-up resistor to accommodate the minimum CTR."},{"question":"Is TLP2703(TP,E available in tape and reel packaging?","answer":"Yes, the part is offered in both Tape & Reel (TR) and Cut Tape (CT) options.

They are not pin-compatible. For a surface-mount replacement with similar Darlington output and 5000 Vrms isolation, the TLP2703 is a functional match, but verify the CTR range and output current rating against your existing BOM — the TLP2703's 900%–8000% CTR at 500 µA and 80 mA output are within the typical TLP127 specification window."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP2703TPE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP2703TPE when reusing this data.
