7500Vpk isolation — the barrier rating that defines fit
The H11A2FR2VM: Rated for 7500Vpk isolation voltage, this optoisolator provides a reinforced barrier between the input LED and output phototransistor — suitable for applications requiring high-voltage galvanic isolation in industrial power supplies, motor drives, and medical equipment where transient overvoltages exceed standard 5000V ratings. The 20% minimum current transfer ratio at 10 mA forward current means the output transistor conducts at least 2 mA collector current when the LED is driven at 10 mA — a baseline for ensuring the downstream logic or load sees a valid signal across the isolation gap. Typical turn-on and turn-off times of 2 µs each place this part in the medium-speed class for phototransistor optoisolators — adequate for 50/60 Hz line-frequency sensing, relay driving, and status feedback where sub-microsecond switching is not required.
Supplied in a 6-SMD Gull Wing package, the H11A2FR2VM mounts on the PCB surface and reflows with standard lead-free profiles — the Gull Wing leads provide visual solder-joint inspection access and mechanical compliance for thermal cycling.
