It is a semiconductor device composed of three PN junction silicon chips and four-layer structure consisting of three electrodes. SCR three electrodes are called the anode (A), cathode (K) and the gate (G). When the anode of the device to the negative potential (cathode relative terms), the symbol can be seen from the PN junction is reverse, reverse characteristic having a similar diode. When applying a positive potential at the anode of the device (if the gate is not connected to any voltage), within a certain range, the device is still in the high impedance off state. However, when a positive voltage is greater than a certain voltage (called breakover voltage), the device quickly turned on by the transition to the low resistance. When applied between the anode and cathode of the SCR voltage is lower than the transition voltage, the device is turned off. At this point if the rate of the appropriate size of the positive voltage (cathode) on the control electrode, the SCR can quickly be excited and turned on. SCR Once turned on, the gate loses its control action. That is, turned to retreat to the gate voltage thyristor is still turned on, only the device current is reduced below a certain value or a voltage between the cathode and the anode is reduced to zero or negative, the device before resuming to the closed state. Since the establishment of Port-Electronics is fully committed to the SCR power control components sales agent services and programs, product applications covering small household appliances, power tools, dimmers, straight hair, lighting control and other consumer electronics and industrial control and so on.
