The LTV-816S-TA1-V-D is a phototransistor optocoupler manufactured by Lite-On Inc. This device provides electrical isolation between circuits, which is essential for protecting sensitive components from high voltages and preventing ground loops. It achieves this isolation using an infrared emitting diode (IRED) and a phototransistor within a single package.

Applications

• Industrial Control Equipment
• Programmable Logic Controllers (PLCs)
• Power Supplies
• Microcontroller Input/Output Isolation
• Signal Transmission in Electrically Noisy Environments

Features

• High Isolation Voltage: Provides substantial electrical isolation between input and output.
• Compact Package: Allows for high-density board mounting.
• CTR (Current Transfer Ratio): The optocoupler has a specified current transfer ratio, crucial for consistent performance.
• RoHS Compliant: Meets environmental standards for hazardous substance reduction.
• Low Input Current: Requires minimal current to activate the input LED.

Benefits

• Enhanced Safety: Protects circuitry from high voltage transients and surges.
• Improved Signal Integrity: Prevents ground loops and reduces noise in signal transmission.
• Simplified Circuit Design: Eases the implementation of isolation in various designs.
• Increased Reliability: Minimizes the risk of damage from electrical disturbances.
• Cost-Effective: Provides a simple and economical method for electrical isolation.

Additional Details

The LTV-816S-TA1-V-D works by converting an electrical signal to light using the IRED. This light then activates a phototransistor, completing the circuit and transmitting the signal without a direct electrical connection. This optical coupling provides the necessary isolation.

The 'TA1' suffix is likely a packaging or testing specification. The 'V' and 'D' likely indicate further specific characteristics such as voltage rating or test parameters relevant to the application. The 'S' often denotes a surface mount package style.
