ILQ5XG

Transistor, Photovoltaic Output Optoisolators Overview

The ILQ5XG is a quad-channel phototransistor output optocoupler manufactured by Isocom Components. It features four independent channels within a single DIP-16 package, providing electrical isolation between input and output circuits. The device utilizes an infrared LED coupled to NPN silicon phototransistors. Key electrical specifications include a minimum collector-emitter breakdown voltage (BVCEO) of 70V and a high isolation voltage rating of 5300Vrms. The typical current transfer ratio is specified at 130% with a maximum forward current of 60mA. Operating temperatures range from -40°C to 100°C.
