The 20 % minimum current transfer ratio at 10 mA forward current sets the LED drive budget — for a given collector load resistor, the CTR floor determines whether the output saturates at the minimum forward current. At 10 mA If, the collector can sink at least 2 mA before the Vce rises above the 500 mV saturation ceiling. ## Switching speed and parametric limits Typical turn-on and turn-off times are 2 µs each — this is a general-purpose phototransistor coupler, not a high-speed digital isolator. The 2 µs propagation limits the useful data rate to roughly 250 kbps in a saturated-switching application; above that the output rise time dominates the bit period. Maximum collector-emitter voltage is 30 V, and the LED forward current ceiling is 60 mA — the part suits 5 V or 12 V logic-level isolation but not 24 V industrial rails without a series resistor that keeps Vce within the 30 V limit. Operating temperature spans -55°C to 100°C — the lower end covers military/aerospace cold-soak conditions; the upper end is below the 125°C junction limit of most automotive-grade couplers, so this is an industrial/commercial temperature grade. ## Package — 6-SMD gull wing on reel The gull-wing leads are compatible with standard reflow profiles and allow visual inspection of the solder joints after assembly. Packaged in Tape & Reel — the reel quantity is the procurement unit; partial reels are quoted on request.","metaTitle":"onsemi 4N25FR2VM Optoisolator, 7500Vpk, 6-SMD Gull Wing","metaDescription":"onsemi 4N25FR2VM optoisolator, 7500Vpk isolation, 20% min CTR at 10mA, 6-SMD gull wing package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tape & Reel (TR)","Input Type":"DC","Output Type":"Transistor with Base","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"4N25","Voltage - Isolation":"7500Vpk","Vce Saturation (Max)":"500mV","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"-","Voltage - Output (Max)":"30V","Supplier Device Package":"6-SMD","Current - Output / Channel":"-","Current Transfer Ratio (Max)":"-","Current Transfer Ratio (Min)":"20% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.18V","Turn On / Turn Off Time (Typ)":"2µs, 2µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cdfaf651d7a1a3387e48131363a5f4f6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/4N25FR2VM/alternatives.json"},"ai":{"faq":[{"question":"What is the 4N25FR2VM used for?","answer":"It is a single-channel optoisolator with a phototransistor output and a base pin for bias or speed-up networks.
