Diodes are components that signifigantly affect the flow of electric current passing through them. Zener diodes, a form of diode, are highly specialized to allow flow in one direction and absorb constant voltage in the opposite direction. Within this group of diodes, the SMBZ5929B-E3/5B is a small-signal zener diode designed for applications that need very small component footprints.

Application Field

The SMBZ5929B-E3/5B is often found in consumer electronics, especially portable products where circuit board space is limited. This zener diode is widely used for voltage regulation and voltage protection in these applications. Examples include the regulation of complex clock systems for video processing and the protection of direct current (DC) power sources from overvoltage conditions.

The SMBZ5929B-E3/5B is also intended for use in automotive, communication, and industrial applications. It can be used to protect input lines and provide voltage reference voltage when subjected to power surges, transients, and overvoltage transients. The low capacitance and low leakage current of this zener diode make it suitable for use in a wide variety of automotive, communication, and industrial applications.

Working Principle

The working principle of the SMBZ5929b-E3/5B is based on the principle of a diodes. A diode is a semiconductor device that only allows one-directional current, meaning that when an electrical current is passed through it in one way, it is open, but when the current is reversed, it is closed. At the same time, the SMBZ5929B-E3/5B also allows the reverse current, allowing it to absorb and regulate a set voltage.

The SMBZ51359B-E3/5B has a breakdown voltage of 5.1V, with a maximum current leakage of less than 5mA, and low capacitance rating of 0.8pF. It is capable of handling a maximum capacitance of 500mA, and a maximum power dissipation of 500mW. When it is subjected to high voltage and/or large current, it will absorb the excess energy, protecting the system from damage.

The SMBZ5929B-E3/5B can also provide an relatively stable voltage reference (Vref) in the circuit. As it is a zener diode, it will hold the voltage at the breakdown voltage until a certain amount of power is passing through it. This allows it to maintain the set Vref in the circuit, ensuring the stability of the circuit.

Conclusion

The SMBZ5929B-E3/5B is a versatile zener diode designed for consumer electronics, automotive, communication, and industrial applications. It offers protection from overvoltage and can be used as a voltage reference for circuits. With its small footprint and low power dissipation, it offers an ideal solution for applications where space and power dissipation are at a premium.
