Diodes are widely used in circuit designs to act as rectifiers, switch elements, or for protection. The Zener diode is a special type of diode that works in the reverse-bias mode. BZX384B36-E3-18 is a Zener diode, classified as a single Zener diode. This guide will provide an overview of the BZX384B36-E3-18 application field and working principle.

Application Field

In any case of regulating the output voltage, the BZX384B36-E3-18 diode is the right choice used in constant voltage supply circuits. Furthermore, it is also accessible in inverters and windings used in voltage control and precision voltage divisions in the area of instrumentation and measurements. Additionally, it is applicable in noise suppression and pulse generation where a shorter rise time and decreased reverse current capability is required. With a repetition rate of 75kHz, it can be used in lighting systems like LEDs in outdoor lighting.

Working Principle

The BZX384B36-E3-18 Zener diode is a 2-terminal device, the anode and the cathode. The cathode is positive and the anode negative. When forward voltage is applied to the BZX384B36-E3-18, it turns on and acts as a simple diode allowing current to pass through. At a certain voltage level, called the “Zener voltage”, the diode will start to conduct in the reverse direction. This is the Zener effect.

The Zener effect only happens when the reverse voltage reaches a specific level, known as the “Zener voltage”. The Zener voltage of the BZX384B36-E3-18 is 18 volts. This means that if the reverse voltage increases above 18 volts, the diode will start to conduct in the reverse direction.

When the diode conducts in the reverse direction, it provides a path for current to flow from anode to cathode. This current is known as “Zener current” or “Reverse Current”. The Zener current of the BZX384B36-E3-18 is 500mW. This means that if the reverse voltage increases beyond 18 volts, the Zener current will flow and the voltage will remain at 18 volts. This is known as the “Zener region”.

The voltage regulation of the BZX384B36-E3-18 is very precise with a tolerance of ±1%, ensuring a constant output voltage. It has a power dissipation of 500mW, allowing for a wide range of uses. The diode has a maximum forward voltage of 2V, allowing it to be used in high voltage applications.

In summary, the BZX384B36-E3-18 is a single Zener diode that can be used in many applications and circuit designs. It has a Zener voltage of 18 volts and a Zener current of 500mW, giving it an excellent voltage regulating ability with great precision and power handling.
