Littelfuse has announced an additional five series of high-temperature Alternistor TRIAC switching thyristors. The thyristors are designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 250Vrms.

Littelfuse’s TRIAC thyristors are available in five compact, surface-mount and through-hole packages and expand the product line by making high 150°C maximum junction temperature devices available in 600V to 800V with ratings of 12A, 16A, 25A, 30A and 40A.

Littelfuse’s combination of high temperature capabilities, space-saving packaging and choice of current ratings makes the devices well-suited for IoT smart home applications that require compact design but don’t involve continuous high currents.

The high temperature Alternistor TRIACs include several key benefits including: easier thermal management, especially in applications with limited or no heat sinking, mechanically and thermally robust clip-attach packages offering higher field reliability and enables designers to use smaller board sizes in low power applications.

 

Typical Applications

  • Kitchen and home appliances
  • Tankless water heaters
  • Electric tools
  • Lighting dimmers
