Thyristors - TRIACsTriac, or TRIode for Alternating Current, is a three-terminal device which uses the principle of reverse blocking to allow current to flow in both directions. The T1235H-6T is a 6 Amp, 600V Triac. This family of parts is typically used as an AC power switch, control or sensing devices in electric systems.Working PrincipleThe T1235H-6T remains off even with a valid gate signal until the two main terminals, MT1 (main terminal 1) and MT2, reach the specified threshold voltage. This is known as the Gate Trigger Voltage, and typically has a minimum level of Vgt for T1235H-6T… this is usually referred to as Vgt Threshold.When the applied voltage to the terminals MT1 and MT2 is above Vgt threshold, current can flow from MT1 to MT2 into the Triac. Please note that the two main terminals, MT1 and MT2, can switch roles without any difference since this Triac works in both directions!Application FieldThe T1235H-6T is typically used in the following applications:• Motor Control • Heating Control • Lighting Control• HVAC Control • Electronics Heat Control • Household Appliances• Industrial Automation • Power SupplyThe Triac can be used wherever a power switch is required, and it is considered a cost-effective solution for this type of application because it does not require the active operation of two components for the switch to be closed. It is able to control low voltage, high voltage and high power loads quite easily.The T1235H-6T is particularly well suited for applications that need precise control of inductive loads like motors and transformers, since it can turn on an off at precisely the same time as the AC voltage waveform, allowing current commutation with good efficiency. In addition, this device has fast switching capabilities, allowing it to connect and disconnect the power source rapidly.Safety ConsiderationsTriacs must be used with caution, since they can draw large amounts of current and can be damaged easily by a wrong connection between MT1 and MT2. Improperly applied, this can cause dangerous and damaging currents to be drawn.It is highly recommended to use overheating and overvoltage protection devices in each circuit, as well as ensuring that all connections comply with safety regulations.ConclusionThe 6 Amp, 600V T1235H-6T Triac is a versatile device that can be used for controlling and switching AC power in a cost-effective and efficient manner. Its fast switching capabilities and high efficiency make it a preferred choice for applications that need precise current commutation. Care should be taken to ensure correct installation and to prevent any dangerous currents being drawn.
