The BZX84C18-G3-18 diode is part of a series of Zener diodes, single in this case, used to regulate voltage levels at a given current. It is manufactured by ON Semi and is categorized as a 2 Watt 500 mW device. This diode has a voltage rating of 18 volts (V) and a current rating of 500 milliamps (mA).

Application Field

The BZX84C18-G3-18 diode is most commonly used for voltage regulation. It can be used for numerous digital systems and applications including power supplies, oscillators, and converters. Its wide range of operating temperatures, from -55°C to 150°C, makes it perfect for a variety of conditions. As it is a Zener diode, it is also used to protect other components and systems from potentially damaging voltage or current.

Working Principle

The BZX84C18-G3-18 diode works on the principle of reversed bias polarity. This means that when no current is applied, the diode is in a reverse bias state. When the current is applied, however, the diode turns on and current flows until it reaches the Zener voltage, which is the voltage at which the diode saturates. The diode then begins to reduce or “clamp” any additional voltage above the Zener voltage in order to regulate the overall level. This also helps to protect other components from overvoltage.

The BZX84C18-G3-18 is an excellent choice for applications that require higher power ratings and a wider temperature range. With its high reliability and good temperature stability, it is a great choice for voltage regulation in a variety of digital systems. As with all Zener diodes, it is important to ensure the correct operating conditions in order to prevent damage to the device and any other components in the system.
