In the temperature switch circuit, the 3V zener diode is used to provide a stable reference voltage. When the voltage across the zener diode exceeds 3V, it starts conducting, keeping the voltage across the diode constant. The 3V zener diode, as the name suggests, has a breakdown voltage of 3V. Zener diodes are special types of diodes that operate in the reverse-biased region and maintain a constant voltage across the diode terminals. It allows current flow in one direction, preventing any damage to the circuit due to reversed polarity. The primary function of the 1N4007 diode in the temperature switch circuit is to protect the other components from reverse voltage. The 1N4007 diode is a silicon diode and offers a maximum reverse voltage of 1000V. It is commonly used in power supply circuits to convert alternating current (AC) to direct current (DC). The 1N4007 diode is a widely used rectifier diode that is capable of handling high voltages and currents.

When the temperature exceeds a certain threshold, the resistance of the thermistor changes, triggering the operation of the switch. In the temperature switch circuit, the 10K thermistor is used to sense the surrounding temperature. As the temperature changes, the resistance of the thermistor either increases or decreases, depending on the type of thermistor.

The 10K thermistor is a thermistor with a resistance of 10,000 ohms at 25 degrees Celsius. The base-emitter junction of the transistor controls the current flow through the collector-emitter junction, making it an excellent choice for switching applications.Ī thermistor is a type of resistor that exhibits a change in resistance based on temperature. It has three terminals – the emitter, base, and collector. One of the key features of the C945 transistor is its ability to amplify weak signals, making it useful for audio and radio frequency applications. The C945 transistor can handle a maximum voltage of 50V, making it suitable for many applications. It is a low-power amplifier and switching transistor that offers high current gain and low voltage output. The C945 transistor is a widely used NPN transistor that can be employed in various electronic circuits.
