MOC223M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC223M is a single-channel transistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon photodarlington detector in an 8-pin SOIC-Narrow package. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a peak forward current of 60 mA, and a minimum current transfer ratio of 500%. The device offers an insulation voltage of 2500 Vrms and operates within a temperature range of -40°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type, as variations exist between tube and reel formats. Ensure the selected variant matches the required channel count and pin configuration for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and compliance status before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single isolated channel with high current transfer ratio is required. The photodarlington output provides significant amplification compared to standard transistor outputs. Consider the 30 V collector-emitter voltage limit and 150 mA maximum collector current when designing the load circuit. Verify that the 8-pin SOIC footprint aligns with the assembly capabilities and space constraints of the design.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOC223 series of optocouplers from onsemi. The series includes variants such as the MOCD223M, which features two channels in the same package style. These components are designed for general-purpose isolation tasks where cost-effective, reliable signal transmission between separate electrical domains is necessary.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOCD223M serves as a dual-channel alternative within the same family but differs in channel count. Direct pin-to-pin replacements should be verified against official substitution lists or equivalent datasheets to ensure compatibility with voltage, current, and isolation ratings.
