SCR is a one-way thyristor controlled rectifier SCR electronic components 2P4M, can in effect under external control signal is turned off by SCR C106G, but once turned on, you can not make an external signal it is turned off, can only be removed by reducing the voltage across the load or it is turned off. SCR is a four-way PN junction PNPN composed of three three-terminal semiconductor device compared with having a PN junction diode, the forward one-way thyristor controlled current-control; and has two PN junctions transistor compared difference is that SCR control current of no amplification. SCR triac turn has turned in two directions, turn-off characteristics. Triac is essentially a two-way anti-parallel thyristor SCR, four PN semiconductor structure is formed by NPNPN five percent, three electrodes of semiconductor devices. Because the main electrode structure is symmetrical (both drawn from the N layer), so it's not a one-way thyristor electrode as the anode and cathode were called SCR T405-600T, but very similar to the control section called an electrode A1, the other is called the second electrode A2. The main disadvantage of the triac lower rate of increase in the ability to withstand voltage. This is because the triac is turned on end in one direction, in layers of silicon carrier has not returned to the off-state location, you must take appropriate protective measures. Triac control circuit elements are mainly used for communication, such as temperature control, lighting control, explosion-proof AC switch and DC motor speed and commutation circuit.
