That means the output behaves as a voltage-controlled resistor — no offset voltage, no saturation voltage — so it can pass analog signals from DC up to a few kilohertz without the Vce(sat) error a transistor output would introduce. The 4170 Vrms isolation rating is the galvanic barrier between the input LED and the output FET, tested per the 6-SMD Gull Wing package's creepage distance. ## Switching speed and drive current budget Turn-on and turn-off times are both 45 µs max — symmetrical, which simplifies timing in low-frequency multiplexed or sample-hold circuits. The forward voltage is 1.3 V typ, and the LED can be driven up to 60 mA continuous. At 10 mA forward current the switching times stay near the typical value; pushing to 60 mA reduces turn-on slightly but increases LED stress. The 30 V max output voltage limits the FET drain-to-source swing — fine for 5 V or 12 V logic-level loads, but not for 24 V industrial rails. ## Active lifecycle and sourcing posture onsemi lists the H11F1SM as Active with ROHS3 compliance. Sourced per RFQ against the BOM quantity — no stock-holding claim, but the active status means production lead times are the normal onsemi cycle. ## Temperature grade and board environment Rated from -40°C to 100°C, this covers most industrial enclosures, outdoor telecom cabinets, and automotive cabin applications. The 6-SMD Gull Wing package is a standard surface-mount footprint — no exposed paddle, so thermal coupling to the board is through the leads only. The DC input type means the LED is polarity-sensitive; reverse voltage protection on the input side is the designer's responsibility.","metaTitle":"H11F1SM onsemi Optoisolator, 4170 Vrms, MOSFET Output, 6-SMD","metaDescription":"onsemi H11F1SM Optoisolator, 4170 Vrms isolation, MOSFET output, 1 channel, DC input, 6-SMD Gull Wing.
