The IS181 is an optically coupled isolator consisting of an infrared LED and an NPN silicon phototransistor in a dual in-line plastic package, designed for signal transmission between systems of differing potentials and impedances. It has a 3.85 mm ±0.3 mm spacing between leads, a current transfer ratio of at least 50%, and is rated for an isolation voltage of 3.75 kV RMS or 5.3 kV peak. The device operates from -55°C to +100°C, with a total power dissipation of 170 mW derated at 2.26 mW/°C above 25°C. It meets UL 94 V-0 and is UL approved under File Number E91231. The package is a drop-in replacement for the Toshiba TLP181. The collector-emitter breakdown voltage is 80 V, and the maximum collector current is 50 mA.
