Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XSM' against official Isocom documentation to confirm surface-mount configuration and lead form. Ensure compliance requirements match project standards, as approvals such as UL and VDE are associated with the MOC8108 series. Confirm package dimensions and pinout compatibility during component selection.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface-mount technology is required for single-channel isolation applications. Consider the 5300Vrms isolation rating for safety-critical designs. Evaluate the 2μs/3μs switching speeds against system timing requirements. Verify that the absence of a base connection aligns with the circuit design needs.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8108XSM belongs to the MOC810x series of non-base lead optically coupled isolators. This series is widely recognized for use in power supply applications where reliable galvanic isolation is necessary. The XSM designation indicates a surface-mount variant, distinguishing it from through-hole DIP versions like the MOC8108X.
