Triac - Detection DIP4 pin type ZC TRIAC optocouplers This suggests that if a measure feet and legs do not pass other SCR, it certainly is extremely T2. In addition, the use of TO-220 package triac thyristor BT136S-600E, T2 very often associated with small radiating plate communicating SCR BT134W-600E, thus also determine the triac T2 pole - works Kt16P single phase thyristor voltage regulator / power adjustment trigger plate under the following conditions: B, 1 to maintain conduction, the anode potential is higher than the cathode potential SCR T405-800T, 2, anode current is greater than the holding current, both are indispensable. C, from on to off 1, the anode potential is lower than the cathode potential, 2, anode current is less than the holding current, any of the conditions to the SCR BT136S-600E, being fertile Electronics (certified), SCR by the Dongguan City n Wolfowitz Electronic Technology Limited. 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.
