Application Field

The BZX84J-C22,115 is a type of diode, specifically classified as a Zener diode. It is a single diode, meaning it consists of a single junction that is used as a voltage regulator. It typically operates at low currents, and typically has a low breakdown voltage. This diode is commonly used in electronic circuits to regulate voltages.There are a variety of applications for this diode, including in AC/DC converters, voltage References and protection circuits. In AC/DC converters, this diode can be used to convert AC power to DC power, by using its low forward voltage drop to reduce the amount of power lost in the conversion. In voltage references, this diode can be used to maintain a stable voltage output over a range of input voltages. Finally, this diode can be used in safety circuits, such as fire alarms, to protect sensitive circuits from being damaged by voltage spikes.

Working Principle

Zener diodes, such as the BZX84J-C22,115, are usually constructed from a PN junction diode. They are specifically designed to together operate at a reverse breakdown voltage point. This is done by introducing an amount of dopant impurities into the PN junction.When the voltage is applied in the forward direction, the diode will act as an ordinary rectifier. When the voltage is applied in the reverse direction, the diode will begin to conduct. As the voltage increases, the current through the diode also increases. This is known as the breakdown voltage. This breakdown voltage is determined by the doping or impurity of the diode.When the diode is operating in the reverse breakdown region, the current can be very stable, even with fluctuations in the voltage. This allows the diode to act as a voltage regulator, as the output voltage remains constant, regardless of the input voltage. The amount of current that flows through the diode is limited by the power dissipation of the diode.The BZX84J-C22,115 is a useful diode, mainly due to its low breakdown voltage, low forward voltage drop, and its ability to be used as a voltage regulator. Its applications range from power conversion to safety circuits, making it a versatile device for a variety of applications.
