Procurement Notes
Verify component status as Not Recommended for New Designs (NRND). Confirm RoHS compliance details through official documentation. Ensure packaging type matches project requirements, noting tube packaging availability. Validate pinout compatibility with existing PCB layouts before integration.
Selection Notes
Select this component for applications requiring AC input handling and moderate speed switching. Consider the 80V collector-emitter voltage limit for output circuit design. Evaluate thermal management needs given the 100mW power dissipation rating. Compare current transfer ratio specifications against load requirements to ensure reliable saturation.
Part Context
This part belongs to the TLP184 series of transistor output optocouplers. It shares functional similarities with other variants in the family but differs in specific suffix designations related to packaging or environmental ratings. The standard TLP184 models typically offer similar isolation and switching characteristics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official Toshiba replacement guides for cross-reference data.
