TLP268J(TPL,E(T

The TLP268J is an optoisolator (also known as an optocoupler) manufactured by Toshiba. It is designed to provide electrical isolation between its input and output, making it suitable for various applications in electronic circuits where signal integrity and safety are paramount.

Key Features:

1. Isolation Voltage: The TLP268J typically offers a high isolation voltage, often rated at 5000 Vrms, which ensures that the input and output sides are electrically isolated from each other. This is crucial for protecting sensitive components from high voltages.

2. Input Configuration: The input side of the TLP268J consists of an infrared LED. When a current flows through the LED, it emits infrared light. The input current required to activate the LED is relatively low, making it efficient for various applications.

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. This configuration allows for signal transmission while maintaining electrical isolation.

4. Transfer Characteristics: The TLP268J has a high current transfer ratio (CTR), which indicates the efficiency of the optoisolator in transferring input current to output current. This is an important parameter for ensuring that the output can drive subsequent stages in a circuit effectively.

5. Package Type: The TLP268J is typically 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), allowing for efficient assembly in modern electronic devices.

6. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +100°C, making it suitable for use in diverse environmental conditions.

7. Applications: The TLP268J is commonly used in applications such as:

   • Signal isolation in data communication systems
   • Switching power supplies
   • Microcontroller interfacing
   • Industrial automation systems
   • Medical equipment

8. Electrical Characteristics: The datasheet for the TLP268J provides detailed electrical characteristics, including input forward voltage, output collector-emitter voltage, and switching times, which are essential for designers to understand the performance of the device in their specific applications.

Summary:

The TLP268J from Toshiba is a versatile optoisolator that combines high isolation voltage, efficient signal transfer, and a compact package design, making it an ideal choice for a wide range of electronic applications where safety and reliability are critical.
