BZX84B15-TP Application Field and Working Principle

Classified as a diode, single Zener, the BZX84B15-TP is a general purpose Zener diode intended for voltage regulation, overvoltage protection, and other applications. It is designed to provide an efficient and economical means of transporting current in the device. Its main purpose is to provide a regulating voltage in a circuit, but its application may also include transient voltage suppression and radio frequency interference suppression. It is uniquely designed for high current operation and provides a low leakage current.

Description

The BZX84B15-TP is designed to provide a regulating voltage in a circuit. It is a special type of diode that has a very low Zener voltage range and low reverse leakage current, making it an ideal choice for applications that require precision voltage regulation. It operates using a breakdown voltage between 15 and 16 volts, and can handle up to 1A of current in the forward bias direction.

This diode has an operating temperature range of -65°C to +175°C, making it suitable for use in a wide variety of environmental conditions. Its simple design and ability to handle a large amount of current also make it ideal for use in circuits with high and low frequency signals.

Working Principle

The BZX84B15-TP works by providing a voltage regulating action in a circuit. It is a type of diode known as a Zener diode, and operates by creating a breakdown voltage in a circuit when the power supply is greater than the Zener voltage. During this condition, the diode will allow current to flow from the higher voltage side to the lower voltage side, thus maintaining the voltage on the lower side.

The diode works by having two components, the N-type and the P-type semiconductor, doped with an increasing amount of impurities. This creates a region between the N and P-type semiconductor, known as a depletion zone. When a certain amount of voltage is applied, it causes a breakdown, or avalanche breakdown, in this region, allowing current to flow between the two semiconductor layers.

The operation of the BZX84B15-TP can also provide overvoltage protection and transient voltage suppression. In these two applications, the diode is configured to conduct only when the voltage exceeds the Zener voltage, diverting current away from the circuit and protecting it from overvoltage conditions.

Applications

The BZX84B15-TP is commonly used for voltage regulation, overvoltage protection, and transient voltage suppression in a variety of circuits. It is also used in radio frequency interference suppression, protection of sensitive electronic components, and protection against voltage spikes caused by lightning or heavy electrical surges. It can also be used in neutron detectors, laser diode drivers and gas sensing circuits.
