Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XSM' confirms the surface mount variant and tape-and-reel packaging configuration. Ensure the procurement documentation explicitly states compliance with RoHS directives and relevant safety certifications such as UL and VDE. Confirm that the component matches the 6-pin SOIC physical dimensions required for the target PCB footprint design.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface mount technology is required for high-density board layouts. The unconnected base pin design offers superior noise immunity compared to standard variants in high EMI environments. Verify that the 5300 Vrms isolation rating meets the safety requirements of the application interface. Ensure the operating temperature range covers the expected environmental conditions of the final assembly.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOC81xx series of non-base lead optically coupled isolators. The series utilizes an infrared LED paired with an NPN silicon phototransistor. The 'XSM' designation indicates the surface mount package style, distinguishing it from through-hole DIP or other lead form variations within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other MOC8112 variants with compatible pinouts and electrical ratings. Verify that replacement parts maintain the 6-pin SOIC package and 5300 Vrms isolation specification. Cross-reference manufacturer datasheets to confirm identical current transfer ratio and switching speed characteristics.
