Supply genuine original identification of SCR SCR SCR MURF1620CTOK three poles of the method is very simple, according to the principle of SCR BTA216 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 On the contrary, so the anode and the control electrode of pros and cons to 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 of the diode characteristic is not ideal, the reverse was not completely blocked state thyristor can have a relatively large current through the SCR BTA316, therefore, sometimes the measured gate reverse resistance is relatively small, and very good control characteristics can not explain. Also SCR BTA208, measurement and control in a very positive and negative resistance, 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. SCR performance difference: the knob dial to R × 1 block, for 1 ~ 6A way thyristor, red pen then K pole, black pen turned on simultaneously G, A pole, without departing from the holding pen A black pole Disconnect the G state pole, the pointer should indicate dozens of Europe to one hundred in Europe, this time the SCR has been triggered, and the trigger voltage is low (or trigger current is small). A pole momentary disconnect and then on again, the position of the pointer should be returned ∞, then the SCR is good.
