The diode also has applications in temperature compensation circuits, and as a voltage reference source in high-precision analog circuits.

Working Principle

The BZG03B43-M3-08 Zener diode operates according to the junction breakdown principle. When a power supply is connected to the diode, current flows from the cathode to anode. As the current increases, it eventually reaches a value at which the breakdown of the junction occurs. At this point, the reverse current increases rapidly and the voltage across the diode does not increase more than its breakdown voltage.

Therefore, the diode acts as a voltage regulator and prevents the connected circuit from exceeding the specified breakdown voltage. Since the breakdown voltage is determined by the characteristics of the diode, it makes them extremely useful for voltage regulation. The BZG03B43-M3-08 Zener diode has a reverse breakdown voltage of 43V.

The diode is also equipped with a special copper oxide layer within its construction, which ensures that the breakdown voltage remains consistent even when the current is increased over time. This ensures that the diode maintains a stable voltage output despite changes in current. As a result, the BZG03B43-M3-08 Zener diode is well suited for high-precision voltage regulation applications.
