The LTV-816STA1D-V is a single channel phototransistor optocoupler manufactured by Lite-On Inc. It provides electrical isolation between an input circuit (typically an LED) and an output circuit (a phototransistor). This isolation allows for signal transfer without a direct electrical connection, which is important for safety and noise reduction.

Applications

• Industrial control systems
• Power supplies
• Telecommunications equipment
• Medical devices
• Consumer electronics

Features

• Single channel
• Phototransistor output
• High isolation voltage
• Compact package
• RoHS compliant

Benefits

• Electrical isolation: Provides a high degree of electrical isolation between the input and output circuits, protecting sensitive components and preventing ground loops.
• Signal transfer: Enables signal transfer without a direct electrical connection.
• Noise reduction: Reduces noise coupling between circuits.
• Compact size: Small package allows for high-density circuit designs.
• Environmentally friendly: RoHS compliant, meeting environmental regulations for hazardous substances.

The LTV-816STA1D-V consists of an infrared LED and a phototransistor. When current flows through the LED, it emits infrared light that activates the phototransistor, allowing current to flow in the output circuit. The 'V' likely refers to a specific voltage range or test parameter. Lite-On optocouplers are known for their reliability and performance in a wide range of applications requiring electrical isolation. Key parameters to check in the datasheet include the isolation voltage, current transfer ratio (CTR), forward current, collector-emitter voltage, and operating temperature range.
