A BZX79-B2V4,143 diode, or Zener diode, is a special type of diode which allows current to pass through it in both directions when it reaches a certain breakdown voltage that is greater than the rated forward voltage of the diode. It is mainly used to maintain a constant voltage across a particular circuit. This type of diode measures just 2 millimeters x 0.5 millimeters, and is designed to operate between a forward voltage of 3.5V and 6.6V, and a reverse voltage of 14.3V.

The working principle of BZX79-B2V4,143 diodes is based on the reverse-biased low current breakdown that they are capable of. When the reverse bias voltage reaches a point called the Zener breakdown voltage level, electric current starts to pass through the diode following the Zener effect. This Zener breakdown voltage allows for a stable voltage across the diode and thus maintains a constant voltage throughout the circuit.

BZX79-B2V4,143 diodes are vastly used in many electronic applications both in industrial and consumer grade. Their miniature size and fast switching make them highly appealing for portable applications such as notebooks, cellphones, and other electronic devices. They are commonly used for voltage regulation, voltage clamping for overvoltage protection, input line conditioning, and bias current regulation for high impedance circuits.

In industrial applications, BZX79-B2V4,143 diodes are primarily used in audio power amplifiers, power supplies, battery chargers, and switch mode power supplies. They are also known for their reliability in applications such as electric light control, heater control, and voltage power switches in automotive systems.

The tiny size and high current handling capabilities of BZX79-B2V4,143 diodes make them perfect for providing an absolute steady voltage reference and secure overvoltage protection in a wide range of electrical/electronic equipment. They also offer remarkably power efficiency and high speed response.
