The BZX384B10-G3-18 is a single zener diode from the semiconductor component manufacturer Diodes, Inc. It has a reverse voltage rating of 18V and a power dissipation of 500mW. This diode is designed to regulate and stabilize power supply voltages and functions as a voltage regulator. It also acts as a protection device in circuits, protecting against over-voltage and over-temperature.

A zener diode is composed of a p-n junction and it relies on the Zener effect to operate. When a forward bias voltage is applied to the diode, it will conduct and allow current to flow. But if the voltage is reversed, the diode will not allow any current to flow. When a large reverse voltage is applied to the diode, the electric field of the junction becomes strong enough to cause free electrons to break bonds of covalent crystal lattice, creating electron-hole pairs. The electrons and holes are then accelerated towards the p-n junction by the electric field, creating a current.

The BZX384B10-G3-18 operates under the principle of voltage breakdown, or Zener breakdown. The zener breakdown occurs when the Zener voltage rating is exceeded, and a large current begins to flow through the diode. This diode has a reverse breakdown voltage rating of 18V and a voltage regulation of +/- 5%. The device also features a reverse current rating of 20mA.

The most common application for the BZX384B10-G3-18 is voltage regulation and voltage stabilization. This diode can be used in power supplies as a voltage regulator, such as in handheld electronics. It can also be used in voltage regulator circuits, such as in radios, computers, and in automotive applications. The diode can also be used in protection circuits, protecting the circuit from over-voltage and over-temperature. In these applications, the diode will “breake down” and limit the voltage when it exceeds a certain level.

The BZX384B10-G3-18 is an ideal diode for a variety of applications. It is designed to withstand temperatures of up to 150°C and has an operating temperature range of -25°C to 70°C. The device has a low reverse leakage current and is RoHS compliant. It can be used in a wide variety of applications, from power supplies to protection circuits.
