Original authentic BTA41-600B triac holding current IH at a predetermined temperature, control pole circuit, thyristor maintain the necessary minimum forward current anode. Many new thyristor after another, such as high-frequency applications suitable for fast SCR SCR 2P4M, can be positive or negative trigger signal to control both directions triac conduction can be used to trigger a positive signal into conduction, so that the trigger signal with a negative turn-off thyristors and the like. Single SCR, triac discrimination: first one of the two test poles, if positive and negative test pointer not moving (R × 1 block), may be A, K or G, A pole (one-way controllable silicon) may also be T2, T1 or T2, G pole (for triac). If one has a measurement instructions for tens to hundreds of Europe, it certainly is way thyristor. And a red pen for the connected K-pole, black pen then for G pole SCR T405-800T, the rest is the A pole. If the positive and negative test instructions are tens to hundreds of European SCR T405-600T, certainly for the triac. Then dial knob to R × 1 or R × 10 block retest, which must have a resistance slightly, slightly larger than a red pen is connected to G pole, black pen connects to T1 pole, the rest is extremely T2 .
