Triac - product differentiation triac bidirectional and unidirectional thyristor difference between ordinary thyristor (also known as SCR) SCR is a high-power semiconductor devices T435-600T, mainly used for high-power AC DC converter, voltage regulator and so on. By way thyristor trigger signal (small trigger current) to control conduction (through large current SCR) controllable properties. Triac - Notes TY300 / TY301 Thyristor Surge Module 3: control interference and inductive loads series resistor grid and avoid self-interference at the time of the thyristor blocking capacitors and inductors to prevent oscillation damping from effect, another RC circuit also has accelerated thyristor effect.
