Product Introduction

Overview

The BT139X-800/L02Q is a four-quadrant TRIAC (Triode for Alternating Current) produced by WeEn Semiconductors. This component is designed to handle medium power switching applications and is capable of operating with loads up to 800V and 16A. The BT139X-800/L02Q is particularly useful in applications requiring the switching of AC loads, as it can operate in all four quadrants, allowing it to switch both positive and negative currents with either a positive or negative gate current.

Key Features

  • Four-quadrant operation, allowing it to switch both positive and negative currents with either a positive or negative gate current.
  • Insensitivity to gate noise for improved reliability.
  • High breakdown voltage of 800V and continuous current capability of 16A.
  • TO-220F package for efficient heat dissipation.
  • Capable of handling high currents for short durations.

Applications

  • Motor controllers: For controlling the speed and direction of AC motors.
  • AC load switching: Suitable for switching various AC loads such as lighting, heating, and cooling systems.
  • Pulse width modulators: Used in applications requiring precise control over the power delivered to the load.
  • Medium power switching: Ideal for applications that require medium power switching capabilities.

Q & A

  1. What is the maximum voltage the BT139X-800/L02Q can handle?
    The BT139X-800/L02Q can handle up to 800V.
  2. What is the maximum current the BT139X-800/L02Q can handle?
    The BT139X-800/L02Q can handle up to 16A RMS.
  3. In which package is the BT139X-800/L02Q available?
    The BT139X-800/L02Q is available in the TO-220F package.
  4. What are the key advantages of using a TRIAC like the BT139X-800/L02Q?
    TRIACs can operate in all four quadrants, allowing them to switch both positive and negative currents, and they are insensitive to gate noise.
  5. What are some common applications of the BT139X-800/L02Q?
    Common applications include motor controllers, AC load switching, pulse width modulators, and medium power switching.
  6. How does the BT139X-800/L02Q differ from an SCR?
    The BT139X-800/L02Q can switch both positive and negative currents, whereas SCRs can only operate in one direction.
  7. What is the significance of the four-quadrant operation of the BT139X-800/L02Q?
    The four-quadrant operation allows the TRIAC to switch loads during both the positive and negative half-cycles of an AC waveform.
  8. Can the BT139X-800/L02Q handle high currents for short durations?
    Yes, the BT139X-800/L02Q can handle much higher currents than its rated value for short durations.
  9. What is the power dissipation capability of the BT139X-800/L02Q?
    The BT139X-800/L02Q can dissipate up to 20W of power.
  10. Where can I find detailed technical specifications for the BT139X-800/L02Q?
    Detailed technical specifications can be found in the datasheet available from the manufacturer's website or through distributors like Digi-Key and Mouser.
