Triac - Golden Rule Isolated Triac switch rule 6. If the triac's VDRM serious, unusual moment in the process of power may be exceeded patch SCR, the following measures of One: the series inductance of the load of several μH inductance unsaturated SCR BT136S-600E, to limit dIT / dt; MOV jumper with the power supply, and increase the filter circuit triac on the supply side - Measurement Plastic can thyristor SCR in the practical application, the provisions of the use of I +, I-, Ⅲ- three ways, and to I + and Ⅲ- most widely used in two ways, using the following two methods to discriminate, and the most common Case of small power triac thyristor BT137S-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. Wal-e-leadership in the positive with the staff warmly welcome all inquiries negotiations to create a positive fertile electronic better future.
