Overview
The TCLT1105 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features a phototransistor output with an accessible base terminal, housed in a low-profile 6-SOP, 5-pin surface-mount package. The device provides a high isolation test voltage of 5000Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a typical forward voltage of 1.25V, a maximum DC forward current of 60mA, and a collector-emitter saturation voltage of 300mV. The unit supports a collector output current of 50mA and offers a Current Transfer Ratio (CTR) flexibility ranging from 50% to 150%.
Feature Summary
- Phototransistor output configuration includes an exposed base pin for external circuit control or sensitivity adjustment.
- High dielectric isolation capability rated at 5000Vrms between input and output circuits.
- Low-profile SMD packaging designed for automated assembly and space-constrained applications.
Applications
- Industrial automation signal isolation
- Microprocessor system interface protection
- Power supply feedback loop isolation
Procurement Notes
Verify the specific CTR bin requirement during procurement, as the part number covers a range of 50-150%. Confirm that the 6-SOP, 5-pin package dimensions match the target PCB footprint. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the datasheet for thermal derating curves relevant to the operating environment.
Selection Notes
Select this component when a phototransistor output with base access is necessary for gain control. The 5000Vrms isolation rating suits high-voltage separation needs. Consider the 6µs/5µs switching times for moderate-speed digital signals. The wide operating temperature range supports harsh industrial environments compared to standard commercial grade alternatives.
Part Context
The TCLT1105 belongs to the TCLT11xx series of transistor output optocouplers. This family utilizes Vishay's specialized construction techniques to ensure reliability. The series shares common package styles but varies in CTR ranges and specific electrical characteristics. It serves as a standard solution for galvanic isolation in general-purpose electronic designs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before sourcing alternatives.
