SCR property only when two-way thyristor between the anode and the cathode K A plus a forward voltage, while controlling the inter-electrode and a cathode coupled G needed to trigger the forward voltage thyristor C106M, before is triggered conduction. In this case A, K was low resistance between the conductive state, between the anode A and the cathode K voltage drop of about 1V. After a one-way thyristor controller G trigger pressure even lose, as long as the forward voltage remains between the anode A and cathode K, one-way thyristor conduction state continues to be in the low resistance. Way thyristor detection resistor R * 1Ω multimeter selected block, with red, black and two pen were measured between any two pins to identify positive and negative resistance until a reading of tens of ohms pin SCR, this When black pen pin for the control electrode G, red pen pin cathode K, another empty pin anode A. The black pen then have to determine the anode A, the red pen is still attached to a cathode K. Multimeter pointer should not move at this time. By shorting the anode A short moment and the gate G SCR 2P6M, this time multimeter power block pointer should be deflected to the right, the resistance reading of about 10 ohms. When connected to the anode A black pen SCR 2P4M, cathode K take the red pen, multimeter pointer deflection, indicating that the way thyristor has breakdown. SCR 2P4M, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
