Thyristor (SCR) pin discrimination (2) Identification of damage: ① Ibid. If the measured anode - cathode positive and negative resistance is very small SCR BTA208, instructions have been shorted. If the measured gate - a big positive and negative resistance SCR cathode BTA312, instructions SCR damaged or shorted. ② measuring positive and negative when the gate to the resistance, do not use 10K files, to prevent high-pressure reverse breakdown table gate. How to identify a thyristor three pole, the anode potential is higher than the cathode potential 2, the control of both highly enough forward voltage and current are indispensable to maintain on an anode potential is higher than the cathode potential 2, the anode current is greater than Both are essential to maintain the current from the conduction to shut off an anode potential of less than 2 cathode potential, the anode current is less than any of the conditions to maintain the current 3, the basic fundamental voltage characteristic voltage characteristics of SCR SCR BTA316, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
