Procurement Notes
Verify the specific suffix code on the ordering information to confirm the exact tape and reel configuration or package variant. Ensure that the selected component matches the required current transfer ratio specifications for the target application circuit design before finalizing procurement orders.
Selection Notes
Select this component when base-controlled switching speed is critical for the system performance. Consider the 70V collector-emitter voltage rating and 50mA output current limits to ensure compatibility with the load requirements. Verify that the SOP-5 package dimensions fit the available PCB space constraints.
Part Context
This part belongs to the TCLT series of transistor output optocouplers from Vishay. The series is designed for general-purpose isolation applications, offering a balance between cost-effectiveness and performance. The TCLT1111 specifically distinguishes itself through its base-driven architecture, which allows for external control of the turn-off time.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Vishay resources for cross-reference data if alternative sourcing is required.
