Triac - Golden Rule isolated triac thyristor switch if BT134W-600E with hard-line, spiral wire or shielded cable. Between the gate and MT1 plus resistance 1kΩ or less. High frequency bypass capacitor and resistor in series between the gate. Another solution SCR BT137S-600E, the choice of H series of low sensitivity triac. Rule 5. If dVD / dt or dVCOM / dt can cause problems SCR T405-800T, triac - Golden Rule Isolated Triac switch Rule 6. If the triac's VDRM in serious , unusual moment in the process of power may be exceeded SCR, one of the following measures: a series inductance to the load of a few μH inductance unsaturated to limit dIT / dt; MOV jumper with the power supply and power supply Increasing the filter circuit SCR T435-800T side | SCR | n Wal Electronics Dongguan City is provided by Wal-Electronic Technology Co., Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) strong, credible, FET and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
