The onsemi H11A1FVM is a single-channel optoisolator with a DC input and a phototransistor output that includes a base connection, housed in a 6-SMD gull-wing package.
Isolation and switching performance
Rated at 7500Vpk isolation, the H11A1FVM meets the creepage and clearance requirements for reinforced insulation in many off-line power converter designs. Typical switching times of 2 µs on and off mean this part handles low-to-moderate speed signal isolation — suitable for status feedback, relay drivers, and logic-level translation rather than high-frequency PWM.
Available through independent distribution on a quoted-to-order basis; inventory is lot-specific and confirmed at RFQ.
