Triac Schematics - A method of detecting extremely determination T2 be seen from Figure 6, G very very close to the T1, T2 very far away. Therefore, positive and negative resistance between G-T1 is very small. RXl file with resistance measured between any two feet when SCR C106M, only between the G-T1 exhibits low resistance, positive and negative resistance is only a few dozen in Europe, and T2-G, T2-T1 between positive and negative resistance are infinite. This suggests that, if measured in a foot and other feet do not pass, it certainly is extremely T2. In addition, the use of TO-220 package TRIAC SCR C106G, T2 is usually very little communication with the cooling plate, thus also determine the T2 pole. 2. After distinguishing T1 G pole and pole (1) identify the T2 pole, first assume that the rest of the feet in a foot of Tl pole, the other foot for G pole. (2) the black pen then T1 pole, the red pen then T2 pole, resistance is infinite. Followed by the red pen to T2 and G short for G-pole with a negative trigger signal, the resistance value should be around ten Euro (see Figure 6 (a)), the tube has proved conduction, conduction direction T1 a T2. Then the red pen and G pole disengaged (but still connected to T2), if the resistance value remains unchanged, prove tubes can be maintained after the trigger conduction state (see Figure 6 (b)). Triac Schematics - naming 1, TRIAC: three side: TRIode (take the first three letters); AC semiconductor switch: ACsemiconductor switch (taking the first two letters). Combinations of the above two terms as "TRIAC", Chinese translation meaning "triac switch." Thus "TRIAC" is triac collectively. 2, BCR: bi: Bi-directional (take the first letter); control: Controlled (take the first letter); rectifier: Rectifier (take the first letter). Then a combination of these three groups of the first letter from the English noun: "BCR", Chinese translation meaning "triac." To "BCR" to name a typical triac manufacturers such as Japan's Mitsubishi, such as: BCR1AM-12, BCR8KM, BCR08AM more. 3 SCR 2P6M, BT: bi: Bi-directional (take the first letter); three-terminal: Triode (take the first letter). A combination of more than two words to "BT", but also on the triac product model name, typically manufacturers such as: STMicroelectronics ST companies, Philips -Philips company, are a way to name the triac. Representative models such as: PHILIPS's BT131-600D, BT134-600E, BT136-600E, BT138-600E, BT139-600E, etc., these are four quadrants / non-insulated / triac.
