The BZX384B10-E3-18 is a single-use Zener diode from ON Semiconductor. It is specifically designed for applications where a low forward voltage drop and high-temperature stability are required. The device is widely used in linear and switching power supplies, voltage regulation, voltage regulators, ESD protection, transient protection, and other applications where an extremely low forward voltage drop is necessary. It should not be used in applications where high-frequency switching is required.

The BZX384B10-E3-18 is a 500mW zener diode that operates at a peak repetitious reverse voltage ranging from 16V to 200V. It features a wide maximum operating temperature range of -55°C to +125°C and a very low body leakage current of less than 0.1µA. The device is encapsulated in a standard SOD-128 (Small Outline Diode) package and has a maximum Zener voltage of 1.4V.

The BZX384B10-E3-18 is a highly reliable device that has been designed to meet the demanding requirements of power system application requirements. It has a number of unique features that make it ideal for these applications. The device has an extremely low forward voltage drop of less than 0.4V for forward biased operation and a very low temperature coefficient. The device is also able to tolerate higher reverse voltages than other Zener diodes and can switch very quickly.

The BZX384B10-E3-18 operates on the principle of reverse-biased breakdown. When the device is subjected to a reverse voltage greater than the Zener voltage, it will conduct in the reverse direction. This device is usually used as a voltage regulator in DC power supplies. Zener diodes are commonly used in voltage regulating circuits to maintain a constant voltage level. The device is usually mounted across the input and output of the power supply and the Zener diode is responsible for limiting the output voltage within a certain range. It will also protect the circuit from voltage spikes and other surges that may otherwise damage the circuit.

The BZX384B10-E3-18 can also be used in charge pump circuits as a replacement for linear regulators. The device is also useful for ESD or surge protection applications as it can absorb large amounts of energy during a fault. It can also be used in reverse-biased tandem connections to reduce the overall leakage current of the circuit. In this configuration, the Zener diode is reverse-biased so that the body diode forward voltage drop is avoided.

Overall, the BZX384B10-E3-18 is an excellent choice for applications where an extremely low forward voltage drop is required. The device is reliable and highly efficient. It is well-suited for a variety of power system applications including linear and switching power supplies, voltage regulation, voltage regulators, ESD protection, transient protection, and other applications where an extremely low forward voltage drop is necessary.
