Each channel provides 3750Vrms galvanic isolation between a DC-input LED and a phototransistor output, with a current transfer ratio (CTR) guaranteed between 50% and 600% at a forward current of 5mA. The output transistor is rated for 80V collector-emitter and 50mA continuous current, with a maximum saturation voltage of 300mV. ## Switching speed and timing budget Typical rise and fall times are 2µs and 3µs respectively, with turn-on and turn-off times both at 3µs.","metaTitle":"TLP293-4(E Optoisolator, 3750Vrms, 4-Ch, SO-16","metaDescription":"TLP293-4(E quad transistor-output optocoupler, 3750Vrms isolation, 50-600% CTR, -55°C to 125°C, SO-16.

Both share the same 3750Vrms isolation, 50-600% CTR, 80V output rating, and SOIC package family. The choice is simply how many isolated channels you need per package — the quad saves board space when you need four, the dual is more economical when you need only two."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP293-4E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP293-4E when reusing this data.
