Unlike many photocouplers that accept only DC forward current, this part accepts both AC and DC input, which simplifies the BOM in applications that sense AC line zero-cross or need bidirectional signal transfer. ## CTR spread and switching speed The current transfer ratio ranges from 50% minimum to 600% maximum, both specified at If=5 mA — the wide spread means the designer must design for the minimum to guarantee logic-level output at the load, while the maximum affects the saturation margin and pull-up resistor value. Typical turn-on and turn-off times are 3 µs each, with rise and fall times of 2 µs and 3 µs respectively — suited to low-frequency signal and power-control interfaces. ## Temperature grade and output ratings The output transistor is rated for 80 V maximum collector-emitter voltage and 50 mA continuous current, with a typical Vce(sat) of 300 mV at the rated current — adequate for driving logic inputs, low-power relays, or DC loads within the current limit.","metaTitle":"TLP290(SE Toshiba Optocoupler – 3750Vrms, AC/DC Input","metaDescription":"TLP290(SE Toshiba photocoupler: 3750Vrms isolation, AC/DC input, transistor output, 50-600% CTR at 5mA, -55°C to 110°C, 4-SOIC.

The primary difference is the packaging: TLP290(SE is supplied in tube, while the TLP290(Y-TP,SE variant is on tape-and-reel.

The key difference: TLP291(GR,SE accepts DC input only, whereas TLP290(SE accepts both AC and DC input. If your design uses DC drive only, the TLP291(GR,SE is a direct drop-in alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP290SE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP290SE when reusing this data.
