Triac - Typical applications triac It is also used solid state relay (SSR) and solid-state contactor circuit. Figure 5 is a proximity switch circuit constituted by the triac. R for the thyristor gate current limiting resistor T405-800T, JAG dry reed pipe. JAG usually open, bidirectional thyristor TRIAC is also turned off. Triac - Notes TY300 / TY301 Thyristor Surge Module 3: Interference power grid control inductive loads and to avoid self-interference of 3.2: LC filter circuit constituted by the LC resonant circuit, the low-pass cutoff frequency as f = 1 / 2πIc, and generally low tens of kilohertz frequency.
