The H11A2SM: It provides 7500Vpk isolation between input and output, suitable for high-voltage signal separation in industrial and power-conversion circuits. The current transfer ratio is a minimum of 20% at 10 mA forward current, with a typical forward voltage of 1.18V. Switching is specified at 2 µs turn-on and 2 µs turn-off typical, and the output transistor saturates at 400 mV maximum with a 30V output ceiling. Operating temperature spans -40°C to 100°C, covering industrial and some automotive-adjacent environments. The part is housed in a 6-SMD gull-wing package (6-SMD supplier device package), surface-mount ready.
The H11A2SM is listed as obsolete by onsemi. Sourcing is through independent distribution channels — quantities are lot-specific and confirmed at RFQ.
