Triac, SCR Output Optoisolators Procurement Notes

This component is officially listed as obsolete and no longer manufactured by onsemi. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the production date code and storage conditions to ensure device reliability, as lead times are not applicable for new manufacturing orders.

Triac, SCR Output Optoisolators Selection Notes

Engineers selecting this part should prioritize availability due to its obsolete status. Alternative selection should consider the MOC3081SR2VM as a similar active substitute from the same manufacturer family. Designers must verify that the 800 V VDRM rating meets the specific AC line voltage requirements of the target application before finalizing the bill of materials.

Triac, SCR Output Optoisolators Part Context

The MOC3081FR2VM belongs to the MOC3081M series of Triac and SCR output optocouplers. It is part of onsemi's portfolio of zero-crossing devices intended for high-voltage AC switching. The FR2 suffix indicates the specific surface-mount tape and reel packaging configuration, distinguishing it from through-hole variants within the same functional family.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3081SR2VM is identified as a similar available substitute from onsemi. Verification of pin compatibility and package dimensions is required when transitioning from the obsolete MOC3081FR2VM to active alternatives.
