MOC8105SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8105SMT&R is a surface-mount optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode and an NPN silicon phototransistor in a six-pin package with the base pin left unconnected. The device provides high isolation voltage of 5.3 kVrms and 7.5 kV peak. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.5 V, and a collector-emitter breakdown voltage of 70 V minimum. The nominal current transfer ratio is 50%, with a maximum dark current of 50 nA. Operating temperature ranges from -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the suffix SMT&R corresponds to tape and reel packaging when ordering. Confirm the specific lead form and spacing requirements match the target PCB footprint. Ensure the component meets necessary regional safety certifications such as UL or VDE if required by the end application standards. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high noise immunity is critical due to the unconnected base terminal. It is suitable for applications requiring moderate current transfer ratios around 50%. Consider the surface mount package type for space-constrained designs. Verify that the 5.3 kVrms isolation rating meets the safety requirements of the specific circuit interface. Check compatibility with standard surface mount reflow soldering profiles.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC810x series of non-base lead optically coupled isolators. The series includes variants like MOC8101 through MOC8108, offering different current transfer ratios. The MOC8105 specifically provides a nominal CTR of 50%. These devices are designed for general-purpose isolation tasks where robust performance in noisy environments is required.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include other MOC8105 variants from different manufacturers such as onsemi or Fairchild, provided they share the same 6-pin DIP or surface mount package and electrical characteristics. Verify that replacement parts maintain the unconnected base pin feature and equivalent isolation ratings.
