... The reduction in dc input voltage range permits the use of lower- voltage capacitors and leads to a reduction in power stage stresses and power dissipation. The STR83145 and STR84145 differ only in their maximum ac current rating (10 A and 12 A, respectively). The internal sensitive-gate triac is switched by a temperature- compensated constant-current gate driver driven kHz pulse train to reduce power dissipation ...
