TCLT1110

Overview

The TCLT1110 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base lead for enhanced switching speed and stability. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It is housed in a compact 6-SOP package with five leads, designed for surface mount applications. The component supports a maximum forward current of 5 mA and offers a collector-emitter saturation voltage suitable for low-power digital signal transmission.

Feature Summary

• Integrates a phototransistor with a dedicated base terminal to improve switching performance and reduce storage time.
• Provides robust electrical isolation capability rated at 5000 Vrms for safe signal transfer across potential barriers.
• Utilizes a compact five-lead SOP package configuration optimized for automated surface mount assembly processes.

Applications

• Digital signal isolation in microprocessor interface circuits
• Switching power supply feedback loop control
• Solid-state relay driver stages

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format matches production requirements. Confirm RoHS compliance status aligns with environmental regulations for the target market. Cross-reference the manufacturer part number against official Vishay documentation to validate authenticity and revision history before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and improved switching characteristics are required compared to standard phototransistor couplers. The integrated base lead allows for external biasing to optimize response times. Ensure the operating temperature range and forward current limits fit within the system design constraints for reliable long-term operation.

Part Context

This device belongs to the family of transistor output optocouplers designed for general-purpose isolation tasks. It distinguishes itself through the inclusion of a base connection on the phototransistor side, which facilitates faster turn-off times. The SOP-6L5 form factor ensures compatibility with standard PCB layouts requiring small footprint solutions for industrial and consumer electronics.
