MOCD223VM

Transistor, Photovoltaic Output Optoisolators Overview

The MOCD223VM is a dual-channel transistor output optocoupler manufactured by onsemi, formerly Fairchild Semiconductor. It features a Photodarlington output configuration housed in an 8-pin SOIC-Narrow package. The device provides 2500 Vrms insulation voltage for robust electrical isolation. Key electrical parameters include a minimum current transfer ratio of 500%, a maximum collector-emitter saturation voltage of 1 V, and a peak forward current rating of 60 mA. The unit operates within a temperature range of -40°C to +100°C and dissipates up to 240 mW.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel architecture enabling independent signal isolation paths within a compact surface-mount footprint.
• Photodarlington output stage designed to deliver high current transfer efficiency for sensitive load driving.
• Integrated insulation barrier rated at 2500 Vrms to ensure safety compliance in isolated circuits.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation between logic and power stages
• Solid-state relay driver circuits for AC/DC load switching
• Microcontroller interface modules for noise-immune digital signal transmission

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation as onsemi, resulting from the acquisition of Fairchild Semiconductor. Confirm the specific suffix VM indicates the standard tube packaging format. Ensure the component matches the 8-SOIC physical dimensions and pinout configuration required by the target PCB layout. Cross-reference the RoHS status with the latest official datasheet revision to confirm environmental compliance requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current transfer ratio performance is critical for driving low-current loads directly. The dual-channel design reduces board space compared to single-channel alternatives. Consider the 45 us fall time limitation for applications requiring faster switching speeds. Verify that the 30 V collector-emitter voltage rating aligns with the maximum load voltage in the specific circuit topology.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the MOCD223M series of transistor output optocouplers. It serves as a direct successor to legacy Fairchild Semiconductor parts following the corporate merger. The component is categorized under general-purpose phototransistor optocouplers, distinct from high-speed or logic-output variants. It shares the same internal die structure as other suffixes within the MOCD223 family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include MOCD223R2VM and MOCD223R2V-M. These variants maintain identical functional specifications and pinouts. Verify that any replacement part retains the same SOIC-8 package dimensions and thermal characteristics before integration.
