Thyristors – SCRs are easy to operate, efficient and economical components that are used in a variety of applications. The T727064854DN is a 3-terminal device with a contact rating of up to 24 VDC at 3 A, and is typically used to switch low-voltage loads and devices on and off. The T727064854DN is a semiconductor device with a single cathode. It is a thyristor and operates using the same principles as the standard SCR or TRIAC.

Applications of the T727064854DN

The T727064854DN is a versatile 3-terminal device that can be used to power up or switch off low-voltage applications. It is often used in household appliances as a reliable switch, in place of a manual switch, and is also sometimes used in industrial settings. It is typically used for various AC voltage applications like light dimming, motor speed control and switching, HVAC controls and more.

The T727064854DN can also be utilized in printed circuit boards and industrial automation systems, given its small and convenient size. For higher current, up to 60 A, the T727064854DN can be used in parallel with other SCRs. In addition, the T727064854DN can be used as a temperature sensor and voltage converter in various electrical and electronic circuits.

Working Principle of the T727064854DN

The T727064854DN works based on the principles of thyristors. It is operated by applying a voltage to the Gate (G) terminal of the device. This causes a ‘latch-up’ in the thyristor and the device turns ‘ON’. As long as the Gate voltage is above a certain level, the T727064854DN stays ‘ON’ and will not turn ‘OFF’ automatically. To turn the device ‘OFF’, the Gate voltage needs to be removed or taken to zero or below. Furthermore, it is also possible to bias the SCR with a negative Gate voltage in order to turn it ‘OFF’.

The T727064854DN is designed with an insulated Gate terminal that adds an extra layer of safety. This design allows the Gate to be fed with AC or DC with impunity. Moreover, the device provides a very low trigger voltage which readily allows micro controllers to drive it using small logic ICs. The T727064854DN also features a series of built-in protection features like short-circuit protection, over-voltage protection and temperature protection.

Conclusion

The T727064854DN is a versatile thyristor that is suitable for a wide array of applications. It has a contact rating of up to 24 VDC at 3 A and works on the principles of thyristor SCRs. The device features insulated Gate semiconductor protection and is currently used in various AC voltage operations such as light dimming, motor speed control, HVAC controls and industrial automation systems. Moreover, the T727064854DN has built-in protection features and is capable of being driven by small logic ICs.
