TLP387(TPL,E

The TLP387(TPL,E) is an optoisolator (also known as an optocoupler) manufactured by Toshiba. It is designed to provide electrical isolation between its input and output while allowing signal transmission. This component is particularly useful in applications where it is necessary to separate different parts of a circuit to prevent high voltages from affecting low-voltage components.

Key Features:

1. Isolation Voltage: The TLP387 offers a high isolation voltage, typically around 5000 Vrms, which ensures that the input and output sides are electrically isolated from each other. This is crucial for protecting sensitive components from voltage spikes and noise.

2. Input Configuration: The input side of the TLP387 consists of an infrared LED. When a current flows through the LED, it emits infrared light, which is detected by the photodetector on the output side. The input current can be controlled to achieve the desired output response.

3. Output Configuration: The output side features a phototransistor that is activated by the infrared light from the LED. The phototransistor can switch on and off, allowing it to control larger loads or interface with other digital circuits.

4. Speed and Response Time: The TLP387 is designed for fast switching applications, with a typical rise time and fall time in the range of microseconds. This makes it suitable for high-speed data communication and control applications.

5. Package Type: The TLP387 is available in a compact DIP (Dual In-line Package) form factor, which makes it easy to integrate into various circuit designs. The package is designed for surface mount technology (SMT) as well, allowing for efficient use of PCB space.

6. Temperature Range: The device operates effectively over a wide temperature range, typically from -40°C to +100°C, making it suitable for various environmental conditions.

7. Applications: The TLP387 is commonly used in industrial automation, power supply systems, signal isolation, and data communication. It is ideal for interfacing microcontrollers with high-voltage systems, providing safety and reliability.

8. Electrical Characteristics: The TLP387 has specific electrical characteristics, including input forward voltage, output collector-emitter voltage, and current transfer ratio (CTR), which are essential for designing circuits that utilize this optoisolator.

Conclusion:

The TLP387(TPL,E) from Toshiba is a versatile and reliable optoisolator that provides essential isolation and signal transmission capabilities in electronic circuits. Its combination of high isolation voltage, fast switching speed, and robust design makes it a popular choice for engineers and designers in various applications.
