The PTV4.3B-M3/85A diode is a single Zener diode, made with a variety of materials in order to provide reliable and effective application of electricity. This type of diode is primarily used for voltage regulation, short-term power protection and circuit protection, and current limiting.

Typical applications of this diode include automotive electrical systems as well as a variety of industrial control systems. As an example, it is often used as a voltage regulator in alternators, voltage stabilizers, and electronic motor starters. It is also used in the power supplies of many electronic devices, including wearable medical implants, robotic vision systems, motor controllers, and even consumer electronic products.

This diode is designed with a non-volitive operation which allows it to react quickly to transient voltage increases or decreases. It also has a low power dissipation and high peak current rating, making it an excellent choice for applications that require low-voltage tolerance.

The PTV4.3B-M3/85A diode’s working principle is based on the concept of avalanche breakdown. When a reverse voltage is applied, the electric field created by the applied voltage causes electrons to accelerate and generate carriers of opposite polarity in the depletion region of the diode. As the voltage increases, the electric field increases and the diode breaks down partially, which leads to the formation of a low-resistance path for current to flow. This low-resistance path generates a stabilizing voltage across the diode and electric field.

The diode has a variety of features designed to ensure its performance in a wide range of applications. It has a high peak power dissipation capability and high reverse voltage rating. It also has a low series resistance and low capacitance on the cathode. The device also has a low thermal value, which helps to reduce the possibility of thermal runaway in a system.

In addition, the PTV4.3B-M3/85A diode has a variety of protection features designed to ensure a high reliability. It has an over-voltage protection circuit to prevent transient overvoltages from damaging the device, and an over-temperature protection circuit that shuts down the device when the temperature exceeds a certain level.

The PTV4.3B-M3/85A diode is a versatile and reliable device that can be used in a variety of applications. Its efficient power handling and low-voltage tolerance make it an excellent choice for applications requiring voltage regulation, short-term power protection and circuit protection, and current limiting.
