The FL817 series of devices each consist of an infrared Emitting diodes, optically coupled to a phototransistor detector.
They are packaged in a 4-pin DIP package and available in Wide-lead spacing and SMD option.
Key Features
z Current transfer ratio （CTR：50%-600% at IF=5mA,VCE=5V）
z High isolation voltage between inputc and output （Viso=5000V rms）
z Creepage distance＞7.62mm z Pb free and ROHS compliant z UL/CUL Approved (File No. E340048).
