TCLT1107

Overview

The TCLT1107 is a single-channel optoisolator from Vishay featuring an NPN phototransistor output with a base terminal. It utilizes a 6-SOP, 5-pin surface-mount package designed for compact circuit integration. The device provides high isolation capability with a rated voltage of 5000Vrms between input and output circuits. Electrical performance includes a typical rise time of 3μs and a fall time of 4.7μs. The component supports a maximum forward current of 60mA and offers a current transfer ratio ranging from 80% to 160%. It operates within a temperature range of -55°C to 100°C.

Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal for enhanced switching control and faster response times.
• Provides robust electrical isolation rated at 5000Vrms to protect low-voltage control circuits from high-voltage loads.
• Utilizes a compact 6-SOP, 5-pin surface-mount package suitable for automated assembly and space-constrained designs.

Applications

• Industrial control systems requiring signal isolation
• Computer peripheral interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact variant within the TCLT11 series. Ensure the selected package matches the 6-SOP footprint dimensions in the design layout. Confirm that the 5000Vrms isolation rating meets the safety requirements of the target application environment.

Selection Notes

Select this component when a phototransistor output with a base pin is required for improved switching speed compared to standard variants. Consider the 6-SOP package size constraints and the 5000Vrms isolation requirement. Evaluate the 80-160% current transfer ratio against the load driving capabilities needed in the specific circuit topology.

Part Context

The TCLT1107 belongs to the TCLT11xx series of transistor-output optoisolators manufactured by Vishay Semiconductor Opto Division. This series is characterized by its use of gallium arsenide infrared LEDs coupled with silicon NPN phototransistors. The family is designed for general-purpose isolation applications where moderate speed and high reliability are necessary.

Replacement Considerations

Cross-reference with other Vishay parts in the TCLT11xx series, such as the TCLT1103 or TCLT1109, which share similar electrical characteristics but may differ in package type or specific current transfer ratio ranges.
