Triac - Notes TY300 / TY301 thyristor surge unit and control large inductive loads can interfere with power grids and disadvantages of self-interference, SCR, SCR here to talk about how to avoid these problems in its use, . 1: Sensitivity triac is a three terminal element, but we do not call it two extremely anode and cathode, the thyristor BT136S-600E, but called T1 and T2 pole, G for the gate. Triac - Notes TY300 / TY301 Thyristor Surge Unit 1: Sensitivity controlling the voltage applied to the electrode is positive regardless of the trigger or negative trigger pulse can make the gate turn-on, two-way under four conditions SCR can be triggered conduction, but the trigger sensitivity different from each other. SCR T405-800T, being fertile electronic (online consultation), SCR provided by the Dongguan City, is Wo Electronic Technology Co., Ltd. Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) Dongguan, Guangdong, FET leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Wal-e-leadership in the positive with the staff warmly welcome all inquiries negotiations to create a positive fertile electronic better future.
