Description

The 6N135 is an optocoupler (also known as an opto-isolator) manufactured by Vishay, 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 sensitive components.

Key Features:

  1. Isolation Voltage: The 6N135 offers a high isolation voltage, typically around 5,000 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 LED: The device contains an infrared LED on the input side. When a current flows through the LED, it emits infrared light, which is detected by the photodetector on the output side. The forward voltage drop of the LED is typically around 1.2V.

  3. Photodetector: 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.

  4. High Speed: The 6N135 is designed for high-speed applications, with a typical rise time of around 10 µs and a fall time of about 10 µs. This makes it suitable for data communication and other fast-switching applications.

  5. Wide Operating Temperature Range: The device can operate over a wide temperature range, typically from -40°C to +100°C, making it suitable for various environmental conditions.

  6. Compact Package: The 6N135 is available in a compact 8-pin DIP (Dual In-line Package) or surface mount package, which allows for easy integration into circuit boards and space-constrained applications.

  7. Output Configuration: The output phototransistor can be configured in various ways, including open-collector output, which allows for easy interfacing with different voltage levels and logic families.

  8. Applications: Common applications for the 6N135 include signal isolation in data communication, switching power supplies, microcontroller interfacing, and protecting sensitive components from high voltage transients.

Electrical Characteristics:

  • Input Current (IF): The typical input current required to activate the LED is around 10 mA.
  • Output Collector-Emitter Voltage (VCE): The maximum collector-emitter voltage for the phototransistor is typically around 30V.
  • Current Transfer Ratio (CTR): The current transfer ratio, which indicates the efficiency of the optocoupler, is typically in the range of 100% to 600% depending on the input current.

Conclusion:

The 6N135 from Vishay is a versatile and reliable optocoupler that provides excellent electrical isolation and fast switching capabilities. Its robust design and wide range of applications make it a popular choice for engineers looking to enhance circuit safety and performance.
