7500Vpk isolation, 30% CTR floor — obsolete, sourced per RFQ
The H11A5FR2VM is a single-channel DC-input optoisolator from onsemi with a phototransistor output that includes a base terminal — useful for gain adjustment or external bias in noise-sensitive circuits. Its 7500Vpk isolation rating covers reinforced insulation requirements in industrial power supplies and motor-drive feedback paths, where transient voltages can exceed 5 kV. Minimum current transfer ratio is 30% at 10 mA forward current, with a typical forward voltage of 1.18 V. Switching is symmetrical at 2 µs turn-on and 2 µs turn-off, which suits low-to-medium speed logic isolation up to roughly 250 kbps. onsemi has marked this part Obsolete. The date-code and lot trace are verified on receipt.
Supplied in a 6-SMD gull wing package (6-SMD, Gull Wing per), the H11A5FR2VM is surface-mount and shipped in Tape & Reel (TR) format. The maximum collector-emitter voltage is 30 V, and the forward current limit is 60 mA DC.
