The LTV816S-TP is a surface-mount phototransistor optocoupler manufactured by Lite-On Inc. It consists of a gallium arsenide (GaAs) infrared emitting diode optically coupled to a silicon phototransistor detector. This optocoupler is designed for applications where electrical isolation is required between circuits, especially in space-constrained applications due to its surface-mount design.

Applications

• Power Supplies: Used for feedback isolation in switching mode power supplies (SMPS).
• Industrial Control Systems: Provides isolation for control signals in programmable logic controllers (PLCs) and other industrial automation equipment.
• Motor Control Circuits: Isolates control signals in motor drive applications.
• Data Communication: Provides isolation in data transmission lines to prevent ground loops and noise.
• Measurement and Instrumentation: Protects sensitive measurement equipment from high voltage and noise.

Features

• Surface Mount Package: Designed for automated assembly processes, reducing manufacturing costs and improving throughput.
• High Isolation Voltage: Offers a high level of electrical isolation between the input and output, enhancing safety and reliability.
