Diodes are essential for any power system, and Zener diodes are no exception. Diodes can be used for both linear regulation and switching. The Z47-BO123-G3-18 single Zener diode is one of the more versatile diodes available. It is a robust and proven diode for applications ranging from low-voltage circuitry to high-voltage protection. Uncover the details of the diode\'s applications and working principle in this article.

Application Fields

The Z47-BO123-G3-18 Zener Diode is a large signal Shottky Barrier device with a nominal Zener voltage of 18V. Its low profile small signal form factor, surface mount package, and hermetic seal construction make it well-suited to a wide range of electronic applications. Typical applications of the Z47-BO123-G3-18 include:

• Linear regulation and low-voltage power supplies
• Clamping and wave shaping circuits
• Video and DC/AC signal regulation
• Voltage-level shifting and signal mixing
• High-voltage switching and protection

It is especially well-suited for use in RF and microwave circuits due to its low parasitic capacitance and fast turn-on/turn-off times. It is also highly resistant to thermal shock, making it well-suited for use in varying temperature environments.

Working Principle

The Z47-BO123-G3-18 relies on the diode\'s characteristic behavior when exposed to a forward voltage. Essentially, the voltage applied to the diode drops across the diode, causing current to flow. As the forward voltage increases, the current through the diode also increases. When the applied voltage reaches a certain point, referred to as the Zener voltage, the current will no longer increase, and the voltage will remain at this voltage despite further increases in current.

This diode\'s working principle can be demonstrated in the following circuit diagram. When the diode is forward-biased and the voltage is less than the Zener voltage, current flows freely through the diode. When the voltage reaches the Zener voltage, 18V in this case, the current is limited and the voltage is stabilized. This voltage stabilization is the heart of the diode\'s rationale for use in a variety of electronic applications.

The Z47-BO123-G3-18 is also thermally protected and has a wide range of operating temperatures from -55°C to +125°C. The Zener voltage is also relatively stable over a wide temperature range. This makes the diode well-suited for applications that require stable regulation over varying conditions.

Conclusion

The Z47-BO123-G3-18 single Zener diode is a robust and proven diode for a wide range of applications from low-voltage circuits to high-voltage protection. Its low profile small signal form factor, surface mount package, and hermetic seal construction make it well-suited for use in RF and microwave circuits. The thermal protection and wide range of operating temperatures make it a reliable choice for applications that require stable regulation over varying conditions.
