Supply of new RD-91 package BTA25-600B triac update rate due to the swift pace of electronic components, brand manufacturers and more, so shop merchandise picture for reference only, under normal circumstances were shipped not specified brand made by goods;. For special requirements friends (tail with / brand) before the next one, please contact the owner SCR triac first anode A1 and A2 between the second anode high voltage thyristor 800V, regardless of the polarity of the applied voltage is the forward or reverse, as long as the control electrode G and the first anode A1 plus a polarity between different trigger voltage, you can trigger the conduction low resistance state. In this case A1, A2 between the pressure drop is about 1V. Once triac conduction high voltage thyristor BCA60-1600, even if the loss trigger voltage can continue to maintain the conduction state. Only when the first anode A1, A2 second anode current is reduced high voltage thyristor 1000V, less than maintaining the current or A1, A2 when the voltage polarity between change and no trigger voltage, triac was truncated, this time only to re plus the trigger voltage before conduction. High voltage thyristor 800V, are fertile Electronics (certified), high pressure SCR provided by Dongguan City is fertile Electronic Technology Co., 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.
