ISOCOM ISQ1X 4-Channel Optocoupler, DIP-16, 5.3kV Isolation
ISOCOM ISQ1X 4-channel optocoupler with 5.3kV isolation in a 16-pin DIP package. For industrial control & signal interfacing.
The ISOCOM ISQ1X is a high-performance, 4-channel optically coupled isolator designed for reliable signal transmission in demanding electronic environments. Encased in a compact 16-pin DIP (Dual In-line Package), it integrates infrared light emitting diodes with NPN silicon phototransistors to provide electrical isolation and noise immunity between circuit sections. This high-density mounting component is engineered to interface systems with different potentials and impedances, making it a cornerstone for robust industrial control and data communication systems.
With a formidable isolation voltage rating of 5.3kV, the ISQ1X ensures superior protection against voltage transients and enhances system safety. It features a high collector-emitter breakdown voltage (BVCEO) of 70V minimum and can handle a forward current of up to 50mA, supporting a wide range of interface requirements. The device offers a minimum Current Transfer Ratio (CTR) of 50%, ensuring efficient signal coupling, and has a total power dissipation of 170mW.
