MOC8105SM

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8105SM is a surface-mount optically coupled isolator from the Isocom Components MOC series. It integrates an infrared LED and an NPN silicon phototransistor in a 6-pin SOP package with an unconnected base pin. Key electrical parameters include a maximum forward voltage of 1.5 V, a collector-emitter breakdown voltage of 70 V, and a minimum current transfer ratio of 50%. The device offers high isolation capability with a rated isolation voltage of 5300 Vrms and a peak value of 7500 Vpk. Operating temperatures range from -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount package type and lead configuration. Confirm RoHS compliance status and check for any specific tape and reel packaging requirements if applicable. Ensure the supplier provides valid UL and VDE certification documentation for the component.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface mount technology is required for optocouplers with high noise immunity needs. The unconnected base pin distinguishes it from standard variants, offering better performance in electrically noisy industrial settings. Verify that the 5300 Vrms isolation rating meets the safety standards of the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC810x series of non-base lead optically coupled isolators. The series includes through-hole (STD), extended pitch (G form), and surface mount (SM) variations. All variants share the same internal LED and phototransistor architecture but differ in physical packaging and lead arrangement to suit different PCB mounting technologies.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other MOC810x series parts with compatible packages, such as MOC8102SM or MOC8104SM. Cross-brand equivalents must match the 6-pin SOP footprint, 5300 Vrms isolation, and NPN output characteristics.
