Introduction to SM72480SDE-120/NOPB

The SM72480SDE-120/NOPB is a solid state temperature sensor that has been designed specifically as an over-temperature protection device. It is intended to meet the demands of a wide variety of applications, such as computers, telecommunications systems, industrial and consumer applications. This temperature sensor utilizes a unique two-stage circuit design which provides the capability for both over-temperature protection and precision temperature sensing. The SM72480SDE-120/NOPB offers a precise temperature detection range which spans 10°C to 120°C.

Application Fields of SM72480SDE-120/NOPB

The SM72480SDE is designed to protect against over-temperature conditions in the following applications:• Computers • Telecommunications systems• Automotive systems • Industrial control systems• Home Appliances• Consumer applicationsThe SM72480SDE-120/NOPB is particularly suited for use in applications where precise temperature detection is required. It is also suitable for applications requiring that if the temperature exceeds a predetermined limit, a system shutdown or “cooling off” period is initiated, to prevent expensive damage to the equipment.

Working Principle of SM72480SDE-120/NOPB

The working principle of the SM72480SDE-120/NOPB is relatively straightforward. When the device is triggered by a temperature increase greater than the preset limit, it switches from its normal operating position to its shutdown position. Once in the shutdown position, the device cuts off the current and/or voltage supply to equipment or a system, thereby preventing unnecessary damage due to overheating.When the temperature decreases to a safe level, the device returns to it’s normal operating position. This device also features a hysteric characteristic, which helps to ensure that the temperature remains within the safe limits. The SM72480SDE-120/NOPB has a low voltage application as well. This feature allows the device to be operated from a low voltage supply, allowing it to be used in systems where battery power is necessary.

Conclusion

In conclusion, the SM72480SDE-120/NOPB is an efficient and highly reliable temperature sensor that has been designed to meet the demands of a wide variety of applications. It is capable of sensing temperatures within a very small range, allowing for precise temperature detection. Additionally, it features a two-stage circuit design which provides both over-temperature protection and precision temperature sensing. Additionally, it can be operated from a low voltage supply, making it suitable for use in systems requiring battery power.
