Supply of new RD-91 package BTA25-600B triac thyristor fast because the electron mobility C106G, so the price is not immutable, the cost of goods due to the number of channels of goods and the market demand in each period to do some adjustments; orders transactions within a day or two if there is a new element after the transaction price adjustment can not be asked back for the difference; please contact the owner; and the way thyristor SCR SCR difference is, two-way When SCR SCR T405-600T G pole trigger pulse polarity change, which turned on with the polarity change direction and change, which can control the AC load. And by the way thyristor is triggered only after pass SCR 2P4M, so there is a single bidirectional thyristor points from the anode to the cathode unilateral wizard. Commonly used in electronic production SCR, MCR-100 has a one-way, etc., there is two-way, etc. TLC336. SCR C106G, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd. (www.dgmydz.com) (www.dgmydz.com) is Dongguan, FET leader, 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.
