Supply genuine original SCR SCR MURF1620CTOK Welcome to order with monocrystalline silicon as the basic material P1N1P2N2 four three-terminal device, starting in 1957, because of its characteristics similar vacuum thyratron, so internationally known as Silicon Thyristors, referred to as thyristors T, and because the thyristor rectifier initially at rest areas, it is also known as silicon controlled rectifier elements, referred to as SCR SCR. In performance, not only with unidirectional conducting thyristor resistance, but also has more than silicon rectifier elements (commonly known as "dead silicon") is more valuable controllable. It is only turned on and off states. SCR can mA current controlled power level of electrical and mechanical equipment If more than this frequency components due to a significant increase in switching losses, allowing to reduce the average current through the phase, this time, the nominal current should downgrade. thyristor SCR can be achieved in the circuit AC non-contact control controllable silicon, a small current to control high current, and not as controlled as the spark generated when the relay, and the fast, long life, good reliability. In speed, dimming, voltage regulators, thermostats, and other various control circuits has its presence. SCR is divided into one-way and two-way, the symbol is different. There are three-way thyristor PN junction, the outermost layer of the P and N poles leads to two electrodes, called the anode and cathode, by the middle of the P-pole leads to a control electrode. Way thyristor has its unique features: When reverse voltage anode, or positive voltage anode pole but no voltage control, it is not conducting thyristor BTA212, while the anode and the gate at the same time connected to the positive When the voltage is turned on it will. Once turned on, the control voltage has lost its control action SCR BTA412Y, with or without the control voltage thyristor BTA216, regardless of the polarity of the control voltage, will remain in the conduction state. To shut off, and only the anode voltage is reduced to a critical value, or reverse. Most triac pin is sequentially T1, T2, G from the left to right (the electrode pins down, there is a character of one side of the face). When the trigger pulse applied to the control electrode G of the size or time changes, will be able to change the size of on-current.
