Thyristors - TRIACs

Triacs, which are named after the three-terminal “tri” and ac current, are devices that belong to the thyristor family. Like other members of the thyristor family, triacs are three-terminal devices and they are controlled with the current applied to the gate terminal. When a current is applied to the gate terminal, it triggers the device and can be used to control the voltage or current in the device.

The L6004D6TP is an example of a triac. It is a 600V 4A low-cost medium-power surface-mount triac with a high commutation capability. It has a higher working voltage than many lower power triacs and can be used to switch a variety of ac loads. It is designed for high efficiency and durability in demanding industrial and home appliance applications. This device incorporates an integral gate element to eliminate the need for an external snubber network.

Application Field

The L6004D6TP is widely used in industrial and home appliance applications, such as air conditioners, heaters, fans, pumps, motors, lights, and so on. It is also widely used in residential and commercial lighting control applications, such as dimmer switches, touch dimmer switches, and occupancy sensors. It is suitable for use in distributed control and remote power supply applications. In addition, it can be used in other applications where ac switching is required.

Working Principle

The L6004D6TP is a three-terminal device with a gate, an anode, and a cathode. The gate terminal is used to control the voltage or current in the device. When a current is applied to the gate terminal, a trigger current flows from the anode to the cathode, and the device switches on. When the applied current is greater than the trigger current, the device will switch off. The device has no current flowing through it in the "off" state.

Once the L6004D6TP is triggered, current passes through the device from the anode to the cathode. The current then passes through the load, and then out of the anode to the cathode. As long as the gate current is maintained, the device will remain in the "on" state, and the current will flow through the load at a rate determined by the applied voltage and resistance in the load.

The L6004D6TP is designed to have a high commutation capability which allows it to switch from the "on" to the "off" state quickly. This is beneficial in applications where a fast switching time is required, such as in lighting control applications.

The L6004D6TP is an example of a triac, and it is a versatile application-specific device. It is suitable for a variety of ac loads, and its high commutation capability makes it an ideal choice for lighting control applications.
