MOC208M

Transistor, Photovoltaic Output Optoisolators Overview

The MOC208M is a single-channel optocoupler featuring a GaAs infrared LED input and a phototransistor output with a base lead. It provides 2500Vrms isolation voltage and operates within a -40°C to 100°C temperature range. The device utilizes an 8-SOIC surface-mount package. Key electrical parameters include a minimum current transfer ratio of 40% at 10mA forward current, a maximum collector-emitter saturation voltage of 400mV, and a peak forward current rating of 60mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Single-channel configuration with transistor output including a base terminal for improved switching speed control
• High isolation capability rated at 2500Vrms between input and output circuits
• Surface-mount construction in a compact SOIC-8 package compatible with standard reflow soldering processes

Transistor, Photovoltaic Output Optoisolators Applications

• Feedback control circuits requiring galvanic isolation
• Interfacing systems operating at different potentials and impedances
• General purpose switching applications
• Monitor and detection circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component status as the MOC208M is classified as obsolete and no longer in production by Fairchild Semiconductor. Sourcing may involve surplus or distributor stock only. Confirm RoHS compliance and packaging details such as tape-and-reel quantities against specific supplier documentation prior to acquisition. Cross-reference with active equivalents if long-term supply assurance is required.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel phototransistor output with base access is necessary for circuit design. Ensure the 70V collector-emitter voltage rating meets load requirements. Verify that the 2500Vrms isolation level satisfies safety standards for the application environment. Consider the 8-SOIC footprint constraints during PCB layout planning.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC208M belongs to the family of small outline optocouplers manufactured by Fairchild Semiconductor. It shares architectural similarities with related models like the MOCD207M but differs in channel count. The device represents a standard solution for isolating low-voltage control signals from higher-voltage loads in industrial and consumer electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the MOCD208M and MOCD213M from Fairchild/ON Semiconductor. These alternatives maintain similar dual-channel or single-channel phototransistor configurations and SOIC-8 packaging. Verify pinout compatibility and electrical specifications before substitution.
