Procurement Notes

Verify availability status as the component may be subject to limited supply or factory special order constraints. Confirm RoHS compliance details through official documentation before integration. Ensure the specific suffix matches required packaging formats such as cut tape versus tube configurations. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency during procurement planning.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed requirements is needed. The SSOP-4 package suits space-constrained printed circuit board layouts. Consider the 200% current transfer ratio for efficient drive requirements. Verify that the 40 V collector-emitter voltage rating aligns with the load conditions in the target application circuit design.
