Onsemi MOCD223-M 8-Pin SOIC Darlington Output Optocoupler 60mA 2.5kV

The Onsemi MOCD223-M 8-Pin SOIC Darlington Output Optocoupler is a dual-channel device with a 60mA rating and a 2.5kV isolation voltage, supplied in a surface-mount SOIC-8 package for printed circuit board designs.

Overview

The MOCD223-M combines a gallium arsenide infrared emitting diode, optically coupled to a monolithic silicon photodarlington detector, within a small outline integrated circuit (SOIC) plastic package. Because it is surface-mount, it removes the need for through-hole mounting, helping to save board space and simplify assembly in dense PCB layouts.

Key Features

• Dual-channel design, effectively doubling functionality within a similar footprint
• Minimum current transfer ratio (CTR) of 500% at a forward current of 1mA, supporting efficient signal coupling with low input currents
• Minimum collector-emitter voltage (BVCEO) of 30V
• Isolation voltage rating of 2.5kV for electrical isolation between input and output circuits
• Darlington output with a 60mA rating

Applications

The optocoupler is suited to scenarios requiring reliable isolation and noise immunity, including communications and networking equipment, portable and battery-powered devices, and sensing and instrumentation systems. It isolates signal lines to prevent ground loops and noise transmission, and separates sensitive measurement circuits from noisy control or power sections.

Dimensions and Weight

Width 3.3, depth 1.5 and height 4.3, as provided, with a weight of 0.327 g.

The MOCD223-M is a dual-channel version of the MOC223M, offering a similar footprint with a surface-mountable SOIC-8 package for compact, high-density PCB assembly.
