This 4 A High Temperature Triac solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays.

Sensitive type devices guarantee gate control in Quadrants I & IV needed for digital control circuitry.

Standard type devices normally operate in Quadrants I & III triggered from AC line.

Features:

  • 150°C maximum junction temperature
  • Voltage capability up to 600V
  • Surge capability up to 48A at 60HZ half cycle
  • Solid-state switching eliminates arcing or contact bounce that create voltage transients
  • No contacts to wear out from reaction of switching events
  • Restricted (or limited) RFI generation, depending on activation point of sine wave
  • Requires only a short gate activation pulse in each half-cycle
  • Halogen free and RoHS compliant

Applications:

Typical applications are AC solid-state switches, power tools, home/brown goods and white goods appliances. Sensitive gate Triacs can be directly driven by microprocessor or popular opto-couplers/isolators. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
