ISOCOM ISQ201X 4-Channel Optocoupler, DIP-16, 5.3kV, 75% CTR

The ISOCOM ISQ201X is a high-density, 4-channel optically coupled isolator designed for reliable signal isolation in demanding electronic applications. It integrates infrared light emitting diodes (IR LEDs) with NPN silicon phototransistors in a compact 16-pin DIP package, providing a robust interface between circuits of different potentials and impedances.

This optocoupler is engineered for high isolation performance, featuring a rated isolation voltage of 5.3kVrms (7.5kV peak). It is built to handle a forward current of up to 50mA, with a minimum collector-emitter breakdown voltage (BVCEO) of 70V and a reverse voltage rating of 6V. The component boasts a minimum current transfer ratio (CTR) of 75%, ensuring efficient signal transmission, and has a total power dissipation of 170mW.

All electrical parameters are 100% tested, guaranteeing consistent performance and reliability for critical systems. Its design makes it an ideal choice for applications where electrical noise, ground loops, or voltage differences must be managed.
