Thyristors - TRIACs

T410-600H is a 600 volts 4 amps, 4 pin Triac Thyristor that is widely used in lighting equipment, solid-state relay applications, phase-control applications, heaters, and other AC switching applications. This thyristor device offers high surge capability as well as an advanced diffused structure. It is extremely efficient and has a very low on-state voltage drop, enabling repetitive high-speed AC switching.

Application Field of T410-600H

The T410-600H is widely used in domestic, industrial and commercial applications thanks to its fast switching times, low on-state voltage drop, high surge capability and compact size. This thyristor device has enabled the development of a range of energy efficient AC switching applications, including:

• Lighting equipment
• Solid-state relay applications
• Phase-control applications
• Heaters
• AC switching applications

T410-600H has been especially successful in the lighting equipment and solid-state relay fields thanks to its fast switching times and low on-state voltage drop. It has also been widely used in phase-control applications such as motor drives, incandescent lamps and heater control, as it allows for accurate control of AC power to the load.

Working Principle of T410-600H

The T410-600H is a four-pin thyristor device which utilizes a diffused structure for operation. This diffused structure means that the device operates non-linearity and does not require an external timing circuit for operation. The device is a bidirectional device, meaning that it can be used in both AC and DC applications. On-state conduction is improved through its high current gain, which ensures fast switching times and low on-state current flow. This device is capable of blocking voltages up to 600 volts and can withstand high surge currents of up to 12 Amps. When in an on-state, the device has a very low voltage drop of approximately 2 Volts, ensuring that it works efficiently even under high load currents.

When in use, the T410-600H operates in two distinct modes. The first of which is the triode mode of operation, where it will conduct current in one direction. This mode will remain active until the device reaches the maximum current rating. The second is the quadrant mode of operation, where the device conducts in both directions, and this mode will remain active until the device reaches the maximum rated blocking voltage. The device is capable of switching from one mode to another very quickly, enabling a range of successful AC switching applications.

The T410-600H is an efficient and highly flexible thyristor device which has enabled a range of successful AC switching applications. It offers fast switching times, low on-state voltage drop and high surge capability, making it an ideal choice for domestic, industrial and commercial applications.
