Diodes - Rectifiers - Arrays

The IRKD166/04 is a specialized semiconductor device widely used in a variety of applications. It belongs to a class of devices known as Rectifiers-Arrays and functions as an electronic negative temperature coefficient switch. This device is available in various packages, making it ideal for a range of applications.

Design

The IRKD166/04 is designed to function as an electronic switch. It has a pair of terminals which act as the anode and the cathode. The anode is connected to the power source and the cathode is connected to a load. An NTCR (Negative Temperature Coefficient Resistor) is connected between the two terminals and when the temperature of the resistor changes, the conductive properties of the device change accordingly.

Application Field

The IRKD166/04 is most commonly used for residential applications. Its switchable operation allows for the appliance’s operation to be controlled by temperature, which makes it very useful in controlling air conditioners and other thermal regulating systems. It is also used in a variety of automotive applications including alternators, engines, lights, and starter motors. In addition, it is used in consumer electronic products such as televisions, computers, and other consumer electronics.

Working Principle

The IRKD166/04 functions as an electronic switch. It is a voltage-controlled device that is activated when the voltage across its terminals rises above a certain level. The switch will then close in order to supply power to the device or load it is connected to. When the voltage across the terminals decreases again, the switch will open and disconnect the power source.

The Negative Temperature Coefficient Resistor (NTC) is connected between the two terminals and when the temperature of the resistor changes, the conductive properties of the device change accordingly. As the temperature changes, the current that is allowed through the device also changes according to its temperature coefficient. When the temperature rises above a certain level, the switch will open, cutting off the power supply. When the temperature slows, the switch will close again and supply power.

Advantages

The IRKD166/04 is a very useful device due to its ability to switch electrical current when the temperature changes. This feature makes it ideal for applications where the precise control of temperature is necessary. It also provides better performance than mechanical switches since it does not require frequent maintenance, and it has a longer operating life. In addition, it is durable and does not require additional power supply for its operation.

Conclusion

The IRKD166/04 is a very useful device from Rectifiers-Arrays. Its ability to switch electrical current when the temperature changes makes it an important component in a wide range of appliances, automotive parts, and consumer electronics. It is a reliable and cost-effective solution for temperature control applications, making it a popular choice for many industries that require precise temperature control.
