TYN1225 import supply manufacturers authentic way thyristor Thyristor thyristor characteristic "explosive." However, if the anode or the control electrode is applied reverse voltage thyristor can not be turned on. The role of the control electrode by applying a positive trigger pulse to the thyristor, but can not make it off. So, the method used to make the thyristor is turned off it? Make conducting thyristor is turned off, the anode can disconnect the power supply (Fig. 3 switch S) or to maintain the anode current is less than the minimum conduction (called maintain current). If applied between the anode and cathode of the thyristor is the AC voltage or pulsed DC voltage thyristor BTA208, then, in the voltage zero crossing triac BTA316, thyristor itself off. SCR SCR There are several classifications. (A) press off, conduction and control Category: SCR off their conduction and control methods can be divided into ordinary thyristor, triac, reverse guide SCR, gate turn-off thyristor (GTO), BTG SCR, temperature and light control thyristor SCR other. (B) the pins and polarity classification: SCR their pins and polarity can be divided into two very SCR, three-pole and four-pole SCR SCR. (C) by Package Category: SCR can be classified according to their package SCR metal packaging, plastic and ceramic packages SCR SCR three types. Among them, the metal packaging SCR is divided Stud, flat-shaped, round shell-shaped other; plastic SCR is divided into finned heat sink type and without type two. Thyristor switch (four) by the current capacity classification: SCR can be divided according to the current capacity of high-power thyristor, the power and low-power SCR SCR three. Typically, high-power thyristor more metal shell package, while medium and small power thyristor is to use more plastic or ceramic package. (E) by off-speed Category: SCR turn-off speed can be divided according to their ordinary SCR and high frequency (fast) SCR. Zero trigger - usually thyristor power regulator, that is, when the AC voltage phase sinusoidal AC zero-crossing trigger, must be zero crossings only triggered thyristor conduction.
