TLP250(F)

The TLP250(F) is an optoisolator (also known as an optocoupler) manufactured by Toshiba, designed to provide electrical isolation between its input and output while allowing signal transmission. This device is particularly useful in applications where it is necessary to separate different parts of a circuit to prevent high voltages from affecting sensitive components.

Key Features:

1. Isolation Voltage: The TLP250(F) offers a high isolation voltage, typically around 5000 Vrms, which ensures that the input and output sides are electrically isolated, providing safety and protection against voltage spikes.

2. Input Configuration: The input side of the TLP250(F) consists of an infrared LED. When current flows through the LED, it emits infrared light, which is detected by the photodetector on the output side. 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. The output can typically handle a collector current of up to 50 mA, making it suitable for driving loads directly.

4. Switching Speed: The TLP250(F) is designed for fast switching applications, with a typical rise time of around 100 ns and a fall time of approximately 50 ns. This makes it suitable for high-speed data communication and control applications.

5. Temperature Range: The device operates effectively over a wide temperature range, typically from -40°C to +100°C, allowing it to be used in various environmental conditions.

6. Package Type: The TLP250(F) is available in a compact DIP (Dual In-line Package) form factor, which facilitates easy integration into circuit boards. The package design also aids in minimizing space requirements in electronic assemblies.

7. Applications: The TLP250(F) is commonly used in applications such as:

   • Switching power supplies
   • Motor control circuits
   • Signal isolation in data communication
   • Microcontroller interfacing
   • Industrial automation systems

8. Pin Configuration: The device typically features a 6-pin configuration, with designated pins for the anode and cathode of the LED, as well as collector, emitter, and base connections for the phototransistor.

Summary:

The TLP250(F) from Toshiba is a versatile optoisolator that combines high isolation voltage, fast switching capabilities, and a compact design, making it an ideal choice for a wide range of electronic applications requiring signal isolation and protection. Its robust performance across various temperatures and its ability to handle moderate output currents further enhance its utility in both consumer and industrial electronics.
