The BZX384B12-G3-18 is a single diode from the BZX series manufactured by Diotec Semiconductor. It is a low-cost, low-power, and low-profile solution for use in a variety of applications. The Zener diode provides reverse breakdown protection, ensures that the voltage across it remains within a certain range, and limits the current flowing through it. The BZX384B12-G3-18 is available in a wide range of voltage ratings, starting at 5 volts and extending up to 12 volts.

The maximum power dissipation of the BZX384B12-G3-18 is 500mW, with a maximum reverse operation current rating of 1.2A. Its operating temperature range is −55°C to +125°C and it can store energy up to 400mW. It is available in a 2-pin SOD-323 package and features a high junction capacitance of 2pf.

The BZX384B12-G3-18 is particularly well suited for applications where a low breakdown voltage is required. It can be used in general-purpose rectification, voltage regulation, ESD protection, and other protective applications. It is also used in power supplies for providing peak current and voltage protection, as well as in voltage limiting circuits.

The BZX384B12-G3-18 operates on the principle of negative temperature coefficient resistance. This means that the Zener diode’s resistance decreases as the temperature increases. As a result, when a voltage is applied to the diode, the increased resistance reduces the current flowing through the device, allowing it to provide voltage regulation.

The BZX384B12-G3-18 is also capable of providing surge protection, as it can limit the peak current or voltage in a circuit. When a surge occurs, the device quickly clamps down the voltage or current, protecting the components in the circuit.

Overall, the BZX384B12-G3-18 is an ideal solution for a range of applications where low-power, low-profile components are required. Its high junction capacitance and low power dissipation make it a reliable and cost-effective option for use in a variety of applications.
