Triac - thyristor voltage characteristic way into a forward-biased junction J2, as long as the current is slightly increased SCR BT134W-600E, the voltage will quickly drop, the so-called negative-resistance characteristics. Then J1, J2, J3 three junctions are in forward biased, the SCR will enter the on-state forward conduction state --- SCR BT137S-600E, at this time, its characteristics with the conventional PN junction forward feature Similar triac - works Kt16P single-phase thyristor regulator / power adjustment trigger plate this time, if the gate G a positive trigger signal input patch SCR, BG2 there Baseflow ib2 flows, After BG2 zoom, its collector current ic2 = β2ib2. Because very connected directly to the collector and BG1 BG2 base, so ib1 = ic. SCR BT136S-600E_ positive Wal Electronics (certified) _ SCR provided by Dongguan City is fertile Electronic Technology Co., 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.
