TRIAC BT136

Br 100.00

  • A TRIAC (Triode for Alternating Current) is a 3-terminal, bidirectional electronic component used to control AC power by conducting current in both directions when triggered.
  • The BT136 is a Triac, a three-terminal semiconductor device used for controlling AC power in applications like dimming lights and controlling motor speeds. It is a bidirectional switch that can control current flow in both directions of an AC cycle and is ideal for switching loads of up to 4A with a microcontroller.
  • Maximum Terminal Current: 4A
  • On-state Gate Voltage: 1.4V
  • Gate Trigger Current: 10mA
  • Max Terminal Voltage is 600 V
  • Holding Current: 2.2mA
  • Latching Current: 4mA
  • Available in To-220 Package
  • The BT136 is TRIAC with 4A maximum terminal current. The gate threshold voltage of the BT136 is also very less so can be driven by digital circuits.
  • Since TRIACs are bi-directional switching devices they are commonly used for switching AC applications. So if you looking to switch of control (dim, speed control) an AC load which consumes less than 6A with a digital device like microcontroller or microprocessor then BT136 might be the right for you.
  • Commonly used in: light dimmers, washing machines, motor control, hand tools. Gate trigger current:6-15mA (VAK=12V,RL=100ohm).
  • Other TIRACs BT139, BTA16, BT169, Q4008
  • Often used in light dimmers, motor speed controls, and heater controls, it acts as an electrically controlled switch, allowing small signals to control larger loads.
