Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm the manufacturer designation as Isocom Components 2004 LTD to ensure component authenticity. Check datasheets for exact mechanical dimensions and thermal characteristics relevant to your PCB layout requirements before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for applications demanding high current gain via the Darlington configuration. The exposed base allows for external biasing or speed improvement if necessary. Ensure the 55V collector-emitter voltage rating exceeds the load voltage in your circuit design. Verify that the 6-SMD footprint matches your board assembly capabilities.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MCA series of optocouplers from Isocom Components 2004 LTD. It is functionally similar to other Darlington output isolators but distinguished by its specific voltage ratings and package type. The MCA255 variant typically offers higher breakdown voltage compared to lower-voltage counterparts in the same family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

MCA255SM is a tube-packaged equivalent from the same manufacturer. MOC8050SD is a functional substitute from onsemi with comparable Darlington output and isolation levels, though pinout and electrical specifics should be verified against original schematics.
