BZX384-B27,115

Diodes-Zener-Single is used to regulate the voltage in a circuit, primarily to ensure that no higher than a certain amount of power is supplied to the components or to protect the components from potential damage. The BZX384-B27,115 diode is one type of diode used in the Zener-Single category.

Introduction

The BZX384-B27,115 diode is a silicon-based, non-silicon-based unidirectional semiconductor device. It is a two-layer structure comprised of a p-type and an n-type material. Because of its structure as a diode, it provides fewer volts than Zener diodes of other types. The reverse breakdown voltage rating is around 15 volts, which means that it is suitable for use in low voltage circuits or as a protection diode. The power dissipation of this diode is up to 300mW.

Types of BZX384-B27, 115

The BZX384-B27,115 diode comes in two types: a through-hole type, and a surface-mount type. The through-hole type diode is typically used for through-hole applications, mounted on a printed circuit board (PCB) with its leads soldered directly to the PCB. The surface-mount type diode can be soldered to the PCB through a solder pad, with the use of a rework station.

Features

The BZX384-B27,115 diode has a high current rating of up to 1A, a low leakage current of 3V maximum at 1A, a low capacitance of 5pF maximum at 1MHz, and an operating temperature range of -55 to 125°C. It has a low switching voltage of around 0.6V. Additionally, it is RoHS compliant, making it an excellent choice for lead-free manufacturing.

Applications

The BZX384-B27,115 diode is commonly used in applications where it is necessary to regulate the voltage in a circuit. It is also used for voltage protection and for the generation of thermal protection. It is often used in power supplies, DC/DC and AC to DC converters, and automotive applications. The BZX384-B27,115 can also be used as a voltage limiting device in circuit design applications.

Working principle

A Zener diode allows current flow in one direction and also allows reverse current, known as the Zener breakdown. Under normal conditions, the diode does not allow the current to flow in the reverse direction. But when the voltage level is increased beyond a certain level, known as the Zener voltage or breakdown voltage, the diode initiates a reverse breakdown and allows the current to flow in the reverse direction.

When the current flow is reversed, the diode creates a low resistance path, preventing any further increase in the voltage. Thus, by selecting the Zener voltage, it is possible to prevent the voltage from exceeding a certain level. The BZX384-B27,115 diode is designed to allow a reverse breakdown at 15 volts.
