Diodes - Zener - Single

The MMSZ4690-HE3-08 is a kind of single zener diode that is used for the regulation of voltages. A zener diode is a semiconductor device which is made up of an anode and a cathode with either negatively doped or positively doped silicon. Its fundamental and essential function is to regulate an electrical voltage within a component. The MMSZ4690-HE3-08 diode is also known as a stabilizer diode and they are commonly used in the power conditioning applications.

Application Field

The MMSZ4690-HE3-08 is used in various fields of electronics like; stabilizing capacitors, voltage regulators, voltage detectors, voltage controllers as well as voltage dividers. Additionally, this diode can be used in oscillators, filters, amplifiers and switches as well. Certain power supplies are used to provide external voltages to other components and this zener diode is used in order to restrain the external voltage and provide a steady supply to these components.

Working Principle

The MMSZ4690-HE3-08 uses the “Zener Effect” principle to regulate the voltages. This Zener effect is the process of breakdown of the P-N junction of the diode. A typical diode’s operation is found from the constant voltage format and is formed from the depletion region. The Zener breakdown voltage for the MMSZ4690-HE3-08 can vary from 4.5V to 5.6V which is highly dependent on the temperatures.

In this zener diode the reverse-bias is used, which means the anode is connected to the most negative side of the circuit and the cathode is connected to the positive side of the circuit. The voltage is constant regardless of the current that flows through the diode and that is why it becomes a stabilizer and regulator. The zener diode will also keep the voltage which is below the zener voltage and it will to conduct the current once the voltage is above this zener voltage. This function of the diode will be very useful in the power conditioning and helping stabilize the fluctuations in the voltage.

A reversal of some junctions may take place during working within the diode, which will cause an impact on the junction resistance. This effect is named the “Zener knee” which affects the voltage regulation values until the conditions of the junction gets back uniform. The voltage regulation depends on the type of the component, circuit design and temperature.

In conclusion, the MMSZ4690-HE3-08 diode can be used in different fields of electronics like amplifiers, switches, oscillators, filters and power controllers. They are used to regulate the constant voltage across the components and circuit. The Zener effect of the diode helps in controlling the voltage and current flow and provides stabilized voltage readings.
