TCLT1009

Overview

The TCLT1009 is a single-channel transistor-output optoisolator manufactured by Vishay Semiconductor Opto Division. It provides electrical isolation with a rated voltage of 5000Vrms. The device features an NPN phototransistor output capable of handling a maximum collector current of 50mA and a collector-emitter voltage of 70V. Key electrical parameters include a typical forward voltage of 1.25V to 1.6V, a maximum DC forward current of 60mA, and a saturation voltage of 300mV. The current transfer ratio ranges from 200% to 400% at a forward current of 5mA. Switching characteristics include typical rise and fall times of 3µs and 4.7µs, respectively. It operates within a temperature range of -55°C to 100°C.

Feature Summary

Provides high-voltage isolation between input and output circuits using a single channel configuration.
Utilizes an NPN phototransistor output for reliable switching applications with defined current transfer ratios.
Designed for surface-mount installation in compact 4-SOP packages suitable for automated assembly.

Applications

Signal isolation in general-purpose digital communication interfaces
Switching control in power supply feedback loops
Isolation barriers in industrial measurement systems

Procurement Notes

Verify the specific datasheet revision and ordering information directly with Vishay or authorized distributors. Confirm that the 4-SOP package variant matches the required footprint and soldering profile for the target application. Ensure compliance with RoHS directives if applicable to the manufacturing process.

Selection Notes

Select this component when a single-channel isolation barrier with moderate speed and high CTR is required. The 5000Vrms rating supports robust noise immunity in electrically noisy environments. Consider the 300mV saturation voltage for low-power loss requirements in the output stage.

Part Context

The TCLT1009 belongs to the family of transistor-output optoisolators designed for general-purpose isolation tasks. It offers a balance of performance and cost-effectiveness for applications requiring galvanic separation. The device is part of Vishay's portfolio of semiconductor opto-division products focused on signal integrity and safety.

Replacement Considerations

Consult official Vishay documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution.
