Supply genuine original identification of SCR SCR SCR MURF1620CTOK three poles of the method is very simple, according to the principle of the PN junction, just use a multimeter to 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 Instead triac TG35C60, so the anode electrode and the positive and negative controls do not pass). Between the control electrode and the cathode is a PN junction, so it forward resistance around Europe in a few - a few hundred ohms range, reverse resistance is larger than the forward resistance. But the control electrode is less than ideal diode characteristics, the reverse was not completely blocked state triac bta26, can have a relatively large current through, so sometimes the control electrode measured reverse resistance is relatively small, and can not explain very good control characteristics. Also triac TG25C60, in a very positive and negative control when measuring the resistance of the multimeter should be placed on R * 10 or R * 1 block to prevent the reverse breakdown voltage is too high the control electrode. If the measured positive and negative elements of yin and yang is very short or very short-circuiting the anode and control, or the control electrode and cathode reverse short-circuit or open circuit control electrode and cathode, indicating element is damaged. 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, as fast thyristor suitable for high frequency applications, you can use positive or negative trigger signal to control both directions triac conduction can be used to make a positive trigger signal conduction , with a negative trigger signal so that the thyristor is turned off and so on. Triac TG25C60, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Dongguan City is Wal-Electronic Technology Co., Ltd.
