Littelfuse Expands High-Temperature TRIAC Thyristor Series

October 10, 2019 Alix Paultre

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

The devices offer a combination of robust clip-attach assembly design and high maximum operating junction temperature for the high surge capability needed to withstand short-duration overload conditions. High-temperature TRIACs are available in these packages: TO-220AB, TO-220 Isolated, TO-263 (D2-PAK), TO-218 Isolated (TOP3 Ins), and TO-218X Isolated with loop leads.
