High-Temperature Thyristor Series for Thermal Management


Ideal for IoT smart home applications including appliances, lighting and controls

CHICAGO — Littelfuse, Inc. announced an additional five series of high-temperature.

Available in five compact, surface-mount and through-hole packages, these components expand the Littelfuse TRIAC 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.

This combination of high temperature capabilities, space-saving packaging and choice of current ratings makes them well-suited for Internet of Things (IoT) smart home applications that require compact design but don’t involve continuous high currents. Potential applications including:

  • Kitchen and Home Appliances

  • Tankless Water Heaters

  • Electric Tools

  • Lighting Dimmers

The high-temperature Alternistor TRIACs include these key benefits:

  • Easier thermal management, especially in application with limited or no heat sinking.

  • Mechanically and thermally robust clip-attach packages offer higher field reliability.

  • Enables designers to use smaller board sizes in low power applications.

  • Ensures higher surge capability to withstand short-duration overload conditions.

    High-temperature TRIACs are available in these popular packages: TO-220AB, TO-220 Isolated, TO-263 (D2-PAK), TO-218 Isolated (TOP3 Ins) and TO-218X Isolated with loop leads unique to Littelfuse.
