AC Switches/TRIACS

AC_Switches _TRIACS
As bidirectional ac switches with three electrodes, triacs precisely control the flow of electric current in many applications. They serve as rectifiers, dc power converters, and motor controllers, and you will often find them in circuitry for ac motors, light dimmers, thermostats, and tankless water heaters. Littelfuse produces triacs and triac-based thyristor modules in a wide variety of shapes and sizes. We engineer our triacs to deliver space and weight savings, as well as excellent temperature and power cycling.
  • Vdrm from 200 V to 1.2 kV
  • I t(rms) from 800 mA to 88 A
  • I drm at Vdrm 25 °C form 0.002 mA to 50 mA
  • I qt(max) below 50 mA
  • I tsm at 60 Hz from 105 A to 500 A
  • Capable of withstanding high surge currents
  • Minimize or eliminate need for snubber diodes
  • Solid-state switching eliminates arcing or contact bounce that create voltage transients
  • No contacts that can wear out
