Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation as onsemi, which acquired Fairchild Semiconductor, when sourcing this component. Confirm the specific suffix SR2M corresponds to the reel or tape-and-reel packaging format required for your production line. Ensure RoHS compliance documentation is available from the supplier. Cross-reference the part number with official onsemi datasheets to confirm pinout and electrical specifications match your design requirements before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high voltage isolation is required between input and output sides of a circuit. The 400 V collector-emitter voltage rating makes it suitable for driving higher voltage loads compared to standard logic-level optocouplers. Consider the SMD-DIP-6 package footprint during PCB layout. Verify that the current transfer ratio meets the drive requirements of the downstream load. Check thermal management needs given the 420 mW power dissipation limit.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the MOC8204M series of transistor output optocouplers. The series is designed for general-purpose isolation applications where reliable signal transmission across potential differences is necessary. The MOC8204SR2M variant specifically denotes the surface-mount version with the associated packaging suffix. This family offers a balance of performance and cost-effectiveness for industrial and consumer electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The MOC8204SM is a through-hole equivalent in the same series. Direct replacements should maintain similar isolation voltage and output transistor characteristics. Verify pin compatibility and package dimensions when substituting. Consult official substitution guides from onsemi for qualified alternatives.
