The BZX79-C62,143 diode is a single zener diode that belongs to the BZX79 series of diodes. It has a breakdown voltage of 6.2V and an operating reverse voltage of 6.3V. This makes it an ideal choice for low-voltage applications requiring reliable and consistent operation. The BZX79-C62,143 diode is a particularly useful component when used in power supplies, voltage regulators, switching circuits and other applications. Additionally, this diode can also be used as a noise suppression device and for impedance matching in various circuits.

Working Principle

The BZX79-C62,143 diode is a single zener diode that works on the principle of the zener effect. In this effect, when a reverse voltage is applied across a diode, the applied voltage creates a depletion region in the diode. As the reverse voltage is increased, the depletion region expands and, eventually, the reverse breakdown voltage of the diode is reached, at which point the current flowing through the diode sharply increases. The reverse breakdown voltage of the BZX79-C62,143 diode is 6.2V, which means that any voltage applied across it that is higher than 6.2V will cause a sharp increase in current.

The diode also has a reverse saturation current which is the amount of current that can flow through the diode when a reverse voltage is applied below its breakdown voltage. This current increases with temperature and is also known as the ‘knee’ current of the diode. The reverse saturation current of the BZX79-C62,143 diode is typically 1.5 nA, which is very low. This ensures that the diode does not leak too much current when it is in reverse bias and works efficiently.

Application Field

The BZX79-C62,143 diode has a wide range of applications, including power supplies, voltage regulators, switching circuits, noise suppression, impedance matching and other applications. It can be used in power supplies where it can protect any other components in the circuit from too much voltage, and it can also be used as a voltage regulator to provide a constant output voltage.

The diode is also often used in switching circuits to switch off other electrical components when the voltage reaches a certain level, and it can also be used in noise suppression to protect sensitive components from any external noise or interference. Additionally, it can be used for impedance matching to ensure that the impedance of various components in the circuit is the same, allowing for the most efficient operation. Finally, the diode can also be used in various other applications where a reliable, consistent voltage source is needed.
