Diodes are electronic devices with two distinct terminals that are used in a variety of applications. A single diode, such as the SE70PB-M3/87A, is an ideal component for rectifying AC power, controlling current flow and preparing the power for use in an application. This article will explain the application field of the SE70PB-M3/87A and its working principle in detail.

Application Field

The SE70PB-M3/87A is a silicon planar diode in a plastic envelope. It is often used as a rectifier diode, which means it is capable of converting AC power into DC power. This type of diode is designed to be used with low power electronic circuits, having current oscillations between 0.5A and 1A.

It is often used in power supplies, motor control, vehicles, product testing equipment, and many other electronic devices that require rectified power as their main power source. The SE70PB-M3/87A is also used in low frequency ovens, which require for the condition of interchangeability.

Working Principle

The SE70PB-M3/87A is a single-terminal (anode) device with the ability to perform a rectifying function. The diode structure consists of single layer of silicon to form a PN junction between the two terminals. When a positive current passes through the anode, the PN junction will provide a rectifying function to produce a positive voltage while blocking any negative voltage. The diode can be reversed into a blocking direction, in which the incoming current will be blocked by the junction.

In addition, the device is also capable of rectifying and blocking the high frequency oscillations, which are usually the cause of disturbances in electronic circuits. This is done by its capacitance, which stores the charge from the incoming current and delays the signal before releasing it. This process can help to reduce or eliminate the disturbances in a power signal, which ensures smooth operation of the equipment.

The SE70PB-M3/87A also features a reverse breakdown voltage, which is designed to regulate the flow of current and to protect the device from damage. The overall capacitance and voltage of the diode allow for low power consumption and higher efficiency when compared to other types of diodes.

In summary, the SE70PB-M3/87A is an ideal component for rectifying AC power and preparing it for use in various applications. It is used in many types of electronic circuits, due to its small size, low power consumption, high efficiency, and reliable performance. The working principle of the diode lies in its ability to rectify AC power and block high frequency oscillations, providing a reliable source of power to the device.
