It provides 2500 Vrms of galvanic isolation between input and output, making it a straightforward fit for isolating digital signals in power supplies, motor drives, PLC I/O modules, and industrial sensor interfaces. The current transfer ratio (CTR) is specified at 100% minimum and 400% maximum, both measured at a forward current of 1 mA. ## Switching speed — adequate for 100 kbps, not for fast digital Rise time is 5 µs typical, fall time 10 µs typical. Turn-on time is 40 µs, turn-off 120 µs. ## Output ratings and temperature range The output transistor is rated for 40 V maximum and 40 mA continuous per channel. Vce saturation is 300 mV maximum at the rated drive — low enough to pull a 5 V CMOS input cleanly to ground. Storage temperature is wider, but that's a handling limit, not an operating spec. ## Package and footprint notes The 4-Mini-Flat package has flat leads — no gull-wing, no J-bend. That means the part sits flush on the PCB, which can help with low-profile designs but also means the leads are less compliant under thermal cycling. On a rework bench, a standard soldering iron with a fine tip can get to the pads, but you'll want to preheat the board to avoid cold joints.","metaTitle":"PS2911-1-F3-AX Optocoupler, 2500 Vrms, 100-400% CTR","metaDescription":"PS2911-1-F3-AX single-channel transistor-output optocoupler. 2500 Vrms isolation, 100%–400% CTR at 1 mA, 40 V output, -55°C to 100°C.

That means at 1 mA LED drive, the output transistor can sink between 1 mA and 4 mA."},{"question":"Is PS2911-1-F3-AX suitable for 5V logic level shifting?","answer":"Yes, with the right pull-up resistor. The output transistor can sink up to 40 mA and saturates to 300 mV maximum, so it can pull a 5 V logic input low through a pull-up resistor. The 40 V output rating gives plenty of headroom for 5 V or 3.3 V logic. Just size the pull-up so the output current stays under 40 mA and the CTR minimum is met."},{"question":"What is a replacement or equivalent for PS2911-1-F3-AX?","answer":"A functional alternative is the PS2801C-4-V-A, which is a four-channel optocoupler with the same DC input, transistor output, 300 mV Vce saturation, and similar switching speed (5 µs rise, 7 µs fall). The main difference is channel count — the PS2801C-4-V-A packs four channels into a single package, which saves board space if you need multiple isolated channels. The PS2911-1-F3-AX remains the single-channel option with the same isolation voltage and CTR range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS2911-1-F3-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS2911-1-F3-AX when reusing this data.
