Thyristor (SCR) pin discrimination (1) Polarity identification: ① range multimeter or appropriated R × 10 × 100 stalls ② anode - cathode forward resistance in more than a few hundred K Ω SCR T405-600T, reverse resistance to ∞. ③ anode - forward resistance between the gate more than a few hundred K Ω. ④ gate - cathode resistor between positive about the SCR in the range of tens of Ω T405-800T, generally reverse resistance than the forward resistance, resistance in the range of several hundred Ω. How to determine the three poles of SCR? How to determine whether the damage to the SCR? Identification of three poles SCR method is very simple SCR 2P4M, according to the principle of the PN junction SCR, just with a multimeter measure the resistance value between three poles can be. Forward and reverse resistance between the anode and the cathode in a few hundred kilohms above, the forward and reverse resistance between the anode and the control electrode over a few hundred kilohms (two PN junction therebetween, and the direction of On the contrary, so the anode and the control electrode of pros and cons to not pass).
