LTV-356T-C

The LTV-356T-C is an optocoupler, specifically a phototransistor optocoupler, manufactured by Lite-On. It is designed to provide electrical isolation between its input and output, making it ideal for applications where signal integrity and safety are paramount, such as in power supplies, data communication, and industrial control systems.

Key Features:

1. Isolation Voltage: The LTV-356T-C typically offers a high isolation voltage, often around 5,000 Vrms, ensuring that the input and output circuits are electrically isolated from each other. This is crucial for protecting sensitive components from high voltages.

2. Input Configuration: The input side of the optocoupler consists of an infrared LED. When current flows through the LED, it emits infrared light, which is detected by the phototransistor on the output side. The forward voltage drop of the LED is typically around 1.2V at a nominal forward current.

3. Output Configuration: The output side features 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. The output can typically handle a collector current of up to 50 mA.

4. Transfer Characteristics: The LTV-356T-C has a high current transfer ratio (CTR), which indicates the efficiency of the optocoupler in transferring input current to output current. This is an important parameter for ensuring that the output can effectively drive subsequent stages in a circuit.

5. Package Type: The device is usually housed in a compact, dual-in-line package (DIP) or surface-mount package (SMD), making it suitable for various PCB layouts and designs. The DIP package typically has 4 pins, while the SMD version may have a smaller footprint.

6. Temperature Range: The LTV-356T-C is designed to operate over a wide temperature range, often from -40°C to +100°C, making it suitable for use in various environmental conditions.

7. Applications: Common applications for the LTV-356T-C include signal isolation in microcontroller interfacing, switching power supplies, and data communication systems. It is also used in industrial automation for isolating control signals from high-voltage systems.

Summary:

The LTV-356T-C from Lite-On is a reliable and efficient optocoupler that provides electrical isolation between input and output circuits. With its high isolation voltage, good current transfer ratio, and wide operating temperature range, it is well-suited for a variety of applications in electronics and industrial systems. Its compact packaging options make it easy to integrate into different designs, ensuring versatility and performance in signal isolation tasks.
