4170 Vrms isolation for motor-drive and industrial signal paths
The H11L2SM is a single-channel optoisolator from onsemi that delivers 4170 Vrms of galvanic isolation between a DC input and an open-collector output. That isolation rating puts it squarely in the range needed for motor-drive feedback, PLC digital inputs, and VFD control interfaces where ground loops and transient spikes are a daily concern. The open-collector output sinks up to 50 mA and operates from a 3 V to 15 V supply rail.
1 MHz data rate with 4 µs propagation delay ceiling
The H11L2SM supports a 1 MHz data rate with typical rise and fall times of 100 ns each, and a maximum propagation delay of 4 µs for both tpLH and tpHL. The input is DC-coupled with a typical forward voltage of 1.2 V and a maximum forward current of 30 mA, so the LED drive can be taken directly from a logic output or a series resistor from a higher-voltage rail.
Active production, industrial temperature, and surface-mount package
No end-of-life notice or successor has been issued — the part is a current catalog item for new designs and replacement builds alike. It is specified over the -40°C to 85°C industrial temperature range, which covers outdoor telecom cabinets, factory-floor panels, and under-hood automotive auxiliary circuits. The 6-SMD gull-wing package (6-SMD, Gull Wing) is a standard footprint for reflow assembly, and the supplier device package is listed as 6-SMD.
