Thyristors - TRIACs TRIACs (triode for alternating current) is a type of thyristor which are “low-voltage, bidirectional semiconductor current controllers” that can be used to control electrical loads or circuits in either direction. Triac was invented by Genisco Technology Corporation in 1957 as an “efficient way to switch alternating current in electronic circuits”. TRIACs have a number of applications ranging from light dimmers to home appliances and consumer electronics. The Q4006DH4TP is a 6A, 400V TRIAC, which is a three-terminal semiconductor switch that is typically used for AC control. It provides bidirectional control of a load in AC applications, such as light dimmers, motor controls, home appliances, and consumer electronics. The Q4006DH4TP is also suitable for mains switching, AC power control, and AC motor speed/temperature controlling applications. typically, a TRIAC is composed of three “fingers”; an anode, a gate and a cathode. When the gate is triggered by a positive pulse applied to one of these fingers, a current flows between the anode and the cathode in a single direction. The current then alternates the direction of flow with each positive and negative half-cycle of the AC waveform. The gating circuit is used to trigger the TRIAC by detecting the zero crossing of the AC waveform. The working principle of the Q4006DH4TP is relatively simple. When a positive voltage pulse is applied to the gate terminal, a small amount of current flows through the gate and into the gate terminal. This current turns on the TRIAC, which allows current to flow between the anode and cathode terminals, allowing for control of the AC current in each direction. When the current needs to be turned off, the TRIAC is triggered a second time, cutting off the flow of current. The Q4006DH4TP is an ideal solution for applications such as home appliance controls, light dimmers, AC motor speed/temperature control, and consumer electronics. It features low power losses, Thermal shutdown protection and a guaranteed trigger circuit. With its low power losses, it is a cost-effective solution for controlling AC current, while the thermal shutdown protection ensures that the TRIAC does not overheat. Lastly, the guaranteed trigger circuit ensures that the TRIAC will turn on reliably, even with small amounts of gate current. To sum up, the Q4006DH4TP is a 6A, 400V TRIAC that provides bidirectional control of a load in AC applications, such as light dimmers, motor controls, home appliances, and consumer electronics. It is composed of three terminal and has low power losses, Thermal shutdown protection, and a guaranteed trigger circuit, making it an ideal solution for AC power control and AC motor speed/temperature controlling applications.
