MMBZ4700-E3-08

The MMBZ4700-E3-08 is a single Zener diode packaged in a SOT-23 small surface mount case, and it is commonly used as a voltage regulator in power supplies and many other applications. It is more commonly referred to as the MMBZ5V6 diode.

This diode is made of silicon, and it has a breakdown voltage of 5.6V at rated power. The zener voltage of this diode is fairly stable over temperature, current, and time. It has an approximate dynamic impedance of 0.09 ohms at 4.7V. The maximum temperature of this diode is 150°C and it is rated for power dissipation up to 500mW.

The MMBZ4700-E3-08 works by controlling the voltage across its two terminals. When the voltage across the two terminals is above a certain threshold, the diode begins to conduct: allowing current to flow from the anode to the cathode. The type of current that is injected into the diode ultimately determines its behavior. For example, when the diode is supplied with AC current, it will act as a voltage regulator, limiting the voltage across its terminals to the zener voltage.

The MMBZ4700-E3-08 is commonly used in linear power supplies and voltage regulators, as well as in RF applications. It is also used in other electronic circuits to provide a stable voltage reference. This diode is particularly useful in applications where space is a concern, as it is extremely small and efficient.

In summary, the MMBZ4700-E3-08 is a single Zener diode packaged in a SOT-23 surface mount case, with a breakdown voltage of 5.6V, and a dynamic impedance of 0.09 ohms at 4.7V. It is commonly used in power supplies, voltage regulators, and RF applications, as well as other electronic circuits to provide a stable voltage reference. This diode offers the advantages of being small and efficient, while providing reliable performance.
