Diodes are semiconductor devices that contain two elements; a P-N junction. This junction, when a voltage is applied, gives rise to rectifying properties that allow current to flow in one direction in the form of a discrete quantity. The main applications of diodes are in rectifying and signal processing, voltage regulation, protection, switching and sensing.The JANTX1N4475US is a single Zener diode that is used to regulate the reverse breakdown voltage in power supplies and any other high voltage DC applications. This diode can be used to provide a stable voltage output when reverse voltage is applied across a device.

Working Principle

The JANTX1N4475US is a silicon zener diode with a reverse breakdown voltage of 12 V minimum. The diode is designed to protect against reverse voltages and to provide a stable output voltage when connected in a circuit. It is usually used in high voltage DC power supplies, where a high reverse voltage may lead to damage of the equipment.When a specified reverse voltage is applied to the diode, it breaks down and becomes \'reverse biased.\' At this point, a small reverse current flows through the diode and the voltage across the diode is fixed at the specified breakdown voltage (in this case, 12 V). This is known as the Zener breakdown voltage.The diode will remain reverse biased and the voltage across the diode will remain fixed at the Zener breakdown voltage until the applied reverse voltage is removed. If the applied reverse voltage exceeds the Zener breakdown voltage, the diode will be destroyed.

Application Field

The JANTX1N4475US is ideally suited for applications where a stable output voltage needs to be maintained. This includes power supplies, voltage regulators, voltage references, and many other circuit protection and voltage regulation applications.The output voltage can be adjusted by changing the Zener diode\'s reverse breakdown voltage. For example, connecting more diodes in parallel will increase the breakdown voltage. This makes the diode ideal for applications that require adjustable output voltages.The JANTX1N4475US can also be used for protecting sensitive electronic circuits from high voltage transients. When reverse voltage is applied to the diode, it will quickly saturate, clamping the voltage to the Zener breakdown voltage and preventing damage to the circuit.This diode can also be used in clipping and clamping circuits, where it can limit the amplitude of oscillations and other waveforms. For example, it can be used in a clipping circuit to clamp an AC waveform to a fixed voltage level. It can also be used for waveform shaping applications, for example, for limiting the amplitude of a sinusoidal waveform to just below the Zener breakdown voltage.In summary, the JANTX1N4475US can be used in a wide variety of applications, from providing a regulated DC output voltage, to protecting circuits from high voltage transients, to clipping and clamping waveforms. Its versatility makes it a popular choice for many circuit designers.
