The IS281 is an optocoupler consisting of an infrared emitting diode optically coupled to an NPN silicon phototransistor, designed for electrical isolation in switching power supplies, industrial controllers, and signal transmission between systems of different potentials. It is housed in a surface-mount, half-pitch 1.27mm mini-flat package and supports an isolation voltage of 3750V RMS. Operating temperature ranges from -55°C to 110°C. The device is RoHS compliant and meets UL 94 V-0 and UL E91231 standards. Collector-emitter breakdown voltage is 80V, with maximum collector current rated at 50mA. Current transfer ratio varies with grade, but all variants share the same package and isolation specifications.
