Procurement Notes

Verify the specific suffix XSM against official Isocom documentation to confirm pinout and mechanical dimensions. Ensure the component meets required isolation voltage standards for your target application. Cross-reference datasheet revisions to confirm material composition and RoHS compliance status prior to integration into production designs.

Selection Notes

Select this component when dual-channel isolation with AC input capability is required in a compact surface-mount form factor. Consider the 100μs switching speed limitations compared to faster logic-output alternatives. Evaluate thermal management requirements given the operating temperature range and power dissipation characteristics inherent to the transistor output stage.

Part Context

This part belongs to the TIL195 series of optocouplers, which are characterized by their ability to handle AC inputs directly without external rectification. The series is widely used in applications demanding robust electrical isolation between low-voltage control circuits and higher-voltage power stages. The surface-mount variant offers space-saving advantages over through-hole equivalents.

Replacement Considerations

Publicly confirmed substitute part numbers for TIL195XSM were not identified in the provided source material. Verify functional equivalence with other dual-channel AC-input optocouplers if direct replacement is necessary.
