BZX84B12-HE3-18

A Zener diode is a two-terminal electronic component, with two concentric layers of a semiconductor material. The BZX84B12-HE3-18 is a specific type of Zener diode, used as a voltage regulator in electronic circuits. It has a wide range of applications, including protecting sensitive electronics from electrical spikes, damping voltage fluctuations, and regulating voltage levels in power systems.

The working principle of a Zener diode is that when a reverse- Biased voltage is applied, the Zener diode will become “forward-biased” once the voltage level reaches the breakdown voltage. This voltage is specific to the type of Zener diode being used and is equal to the Zener voltage for the component. Once the breakdown voltage is reached, the diode will begin to conduct current.

The BZX84B12-HE3-18 is designed to handle up to 18 volts, with a maximum power dissipation of 600 mW and a zener impedance of 15.3 ohms at 10 volts. The component is designed to maintain the voltage level within a predetermined range, while the impedance helps to limit the current flowing through the circuit. This makes it useful for applications where steady and reliable voltage regulation is required.

This Zener diode can be used for a range of applications, such as controlling the output voltage of the switch mode power supply, stabilizing the voltage level of various electronic devices, and protecting sensitive circuits from excessive electrical spikes. It is also possible to construct a voltage regulator using the BZX84B12-HE3-18, along with other components such as resistors, capacitors, and transistors. This will allow the user to customize the regulation to their specific requirements.

In conclusion, the BZX84B12-HE3-18 is a Zener diode, designed for use as a voltage regulator in electronic circuits. The diode can handle up to 18 volts and has a wide range of applications, including controlling and stabilizing voltage levels for sensitive electronics, as well as constructing voltage regulators to meet specific requirements.
