Procurement Notes
Verify the exact part number nomenclature before ordering, as Fairchild Semiconductor integration into ON Semiconductor requires replacing underscores with dashes in system records. Confirm that the specific revision matches your design requirements, as specifications may change without notice. Ensure compliance with life support policies, as these products are not authorized for such critical systems. Validate all operating parameters for your specific application environment.
Selection Notes
Select this component when designing circuits requiring precise analog signal isolation or switching with minimal leakage. The TO-92 package suits through-hole mounting constraints. Consider the thermal resistance limits when determining heat dissipation needs. Verify compatibility with chopper-stabilized amplifier topologies and sample-and-hold timing requirements during the schematic capture phase.
Part Context
This device was originally manufactured by Fairchild Semiconductor and is now distributed under the ON Semiconductor brand following corporate integration. The datasheet indicates it is sourced from process 51. Designers should refer to the J111 document for additional related characteristics. The product status reflects its history as a legacy component managed within the broader portfolio.
Replacement Considerations
Consult the manufacturer's website for updated ordering information and potential cross-reference equivalents. Verify if newer revisions have superseded this specific part number due to system integration changes.
FAQ
