7500Vpk isolation — what it means for the BOM
The H11A3FVM: With a minimum current transfer ratio (CTR) of 20% at 10 mA forward current, the device guarantees that for every 10 mA driven into the LED, at least 2 mA of collector current is available at the output transistor — a key parameter for ensuring the downstream logic or load sees a clean on-state signal across temperature and LED aging.
Package and temperature grade
Housed in a 6-SMD Gull Wing package (supplier device package 6-SMD), this surface-mount optoisolator is supplied in Bulk. The output transistor is rated for a maximum of 30 V collector-emitter voltage and 400 mV saturation voltage at the specified drive current — typical for low-side switching of logic-level loads or PLC input modules.
