LTV-816S-TA1-D3-TX Optoisolators - Transistor, Photovoltaic Output by Lite-On

The LTV-816S-TA1-D3-TX is an optoisolator (also known as an optocoupler) manufactured by Lite-On, designed for applications requiring electrical isolation between different parts of a circuit. This component is particularly useful in protecting sensitive electronic components from high voltages or transients that may occur in the system.

Key Features:

1. Isolation Voltage: The LTV-816S provides a high isolation voltage, typically around 5,000 Vrms, ensuring that the input and output sides are electrically isolated from each other. This is crucial for safety and reliability in various applications.
2. Input Configuration: The device features a gallium arsenide (GaAs) infrared LED as the input element. This LED emits infrared light when current flows through it, which is the basis for the optocoupling mechanism.
3. Output Configuration: The output consists of a phototransistor that is sensitive to the infrared light emitted by the LED. When the LED is activated, the phototransistor conducts, allowing current to flow through the output circuit.
4. Transfer Characteristics: The LTV-816S has a high current transfer ratio (CTR), typically ranging from 50% to 600%, depending on the specific conditions. This means that a small input current can control a much larger output current, making it efficient for signal transmission.
5. Package Type: The component is housed in a compact, 8-pin DIP (Dual In-line Package) form factor, which is suitable for through-hole mounting on PCBs. This design allows for easy integration into various electronic systems.
6. Operating Temperature Range: The LTV-816S is designed to operate over a wide temperature range, typically from -40°C to +85°C, making it suitable for use in diverse environmental conditions.
7. Applications: This optoisolator is commonly used in applications such as signal isolation, data communication, power supply feedback, and interfacing between different voltage levels in electronic systems.
8. Pin Configuration: The standard pin configuration includes pins for the anode and cathode of the LED, as well as pins for the collector and emitter of the phototransistor, along with additional pins for biasing and connection to the circuit.

Summary:

The LTV-816S-TA1-D3-TX from Lite-On is a versatile and reliable optoisolator that provides essential electrical isolation in various electronic applications. Its robust design, high isolation voltage, and efficient signal transfer capabilities make it an ideal choice for engineers looking to enhance the safety and performance of their circuits.
