Introduction to the GDZ9V1B-G3-18

GDZ9V1B-G3-18 is a single Zener diode with a centerline voltage of 9V, a 1 Amp maximum power rating and tolerances up to ±18% maximum. It is a low-cost, low-power, high-stability Zener diode that is typically used in applications that require a wide range of operating temperatures (roughly −40 to +125°C).

Application Field

The GDZ9V1B-G3-18 single Zener diode is an especially useful semiconductor device for many power applications. Its low cost, low power consumption, and high stability make it ideal for use in applications subject to extreme environmental changes, including:

• Over-voltage protection
• Voltage clamps
• Regulated power supplies
• Voltage stabilization
• Surge and spike protection

In each of these applications, the GDZ9V1B-G3-18 provides effective voltage regulation over a wide range of temperatures and other conditions. As a result, it has become the go-to solution for many modern power design projects.

Working Principle

The way the GDZ9V1B-G3-18 works is fairly simple. In essence, it acts as a reverse-biased diode, in that it allows electricity to flow in one direction - from the anode to the cathode- but not the other. As voltage is applied, the diode begins to act like a resistor, and the current will be limited by the Zener breakdown voltage set by the diode. This breakdown voltage depends on the individual diode\'s characteristics and remains relatively stable; so, this property is essential for regulating power sources.

The breakdown voltage of the GDZ9V1B-G3-18 is typically around 9V, although this is subject to tolerance, with a maximum variation of ±18%. This means that when voltage is applied to the diode, the Zener voltage will range from 7.2V to 10.8V. This allows for a good degree of variability in applications, ensuring that the diode can be used in a variety of applications with different voltage requirements.

In addition to regulating the voltage, the GDZ9V1B-G3-18 also has a maximum power rating of 1 Amp. This means that the diode is able to withstand up to 1 Amp of current, with an absolute maximum power rating of 0.8W. This ensures that the diode is capable of protecting against surges or spikes in current without being damaged.

The GDZ9V1B-G3-18 single Zener diode is an incredibly useful device for power applications. Its ability to maintain a relatively stable voltage output over a wide range of temperatures, as well as its high power and current ratings, make it perfect for a variety of applications.
