ONSEMI 2 Channel Optocoupler, SOIC-8, 60mA, 2.5kV

The ONSEMI 2 Channel Optocoupler is a highly reliable semiconductor device designed for electrical isolation in sensitive electronic circuits. It utilises a transistor output to couple signals between an input light-emitting diode and an output phototransistor, completely isolating the two sides and preventing high voltages or electrical noise from interfering with low-voltage control systems. Its robust design makes it an essential component for protecting microcontrollers and logic circuits from potentially damaging voltage spikes or ground loops commonly found in industrial environments.

Housed in a compact SOIC (Small Outline Integrated Circuit) package, this 8-pin device offers a high forward current rating of 60mA and an impressive isolation voltage of 2.5kV, ensuring safe and reliable operation in high-voltage applications. The high current transfer ratio (CTR) of a minimum of 100% indicates excellent efficiency in converting the input optical signal to an output electrical current. With a collector-emitter voltage rating of 70V, it provides sufficient headroom for a wide variety of switching and signal transmission tasks.

Key Applications

This optocoupler is ideal for use in power supply feedback loops, motor drive circuits, and communication interfaces where electrical isolation is mandatory. It is perfectly suited for industrial control systems, medical equipment, telecommunications infrastructure, and consumer electronics that require protection from transient voltages. Its dual-channel configuration allows for the isolation of two independent signal paths within a single, space-saving component.
