ILQ1SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ILQ1SMT&R is a quad-channel transistor output optocoupler manufactured by Isocom Components. It features four independent channels within a single surface-mount package, providing electrical isolation between input and output circuits. The device utilizes an infrared LED coupled to NPN phototransistors for signal transmission. Key specifications include a maximum isolation voltage of 5300Vrms, ensuring robust barrier protection in high-voltage environments. The unit supports a maximum forward current of 60mA per channel and offers a collector-emitter breakdown voltage of 70V. Typical switching characteristics include rise and fall times suitable for general-purpose digital isolation applications.
