The IS281C is an optocoupler consisting of an infrared emitting diode optically coupled to an NPN silicon phototransistor, designed for signal transmission between systems of different potentials and impedances. It is housed in a surface-mount package with a half-pitch of 1.27mm and is available in tape and reel packaging of 1000 pieces per reel. The device supports an isolation voltage of 3750V RMS, operates from -55°C to 110°C, and meets RoHS and UL 94 V-0 standards. Its current transfer ratio (CTR) ranges from 200% to 400% at an input current of 5mA and collector-emitter voltage of 5V. The output saturation voltage is 0.2V max at 10mA input and 1mA collector current. Rise and fall times are 6 to 18 microseconds with a 100Ω load. The device is UL-approved under E91231, Model "THP".
