Introduction

The VS-1N2128RA is a single rectifier diode coded type, designed specifically for use in the application field of high-frequency electrical power transmission. It is optimized for high breakdown voltage and high-forward current capability, making it well suited for a variety of applications using rectification, such as rectified AC current for a voltage-boosting transformer, rectified DC current for a DC power supply, or rectified DC current for a switching power supply. This paper will discuss the features and working principle of the VS-1N2128RA rectifier diode, as well as itsapplication field.

Features of VS-1N2128RA

The VS-1N2128RA has the following features: • High Breakdown Voltage: The VS-1N2128RA has a maximum peak repetitive reverse voltage of up to 1.0kV and a maximum continuous forward current of up to 8.0A. • High-Frequency Operation: The operating frequency of the VS-1N2128RA is up to 300kHz, making it suitable for high-frequency power transmission applications. • Low leakage Current: The leakage current of the VS-1N2128RA is very low; it is typically below 1.0mA. • Low Forward Voltage Drop: The forward voltage drop of the VS-1N2128RA is typically below 0.45V when forward current is 8.0A.

Working Principle of VS-1N2128RA

The working principle of the VS-1N2128RA is based on the principle of rectifying alternating current (AC) power which is widely used in power supplies. It works by allowing current to flow in one direction only, while blocking the current path in the reverse direction. When the diode is forward biased, current is allowed to flow, and when the diode is reverse biased, current is blocked. When rectifying alternating current power, the VS-1N2128RA diode is connected in series with an AC power source such as a transformer, and the load is connected in parallel with the diode. When an alternating voltage is applied to the diode, the diode conducts current during its forward bias and does not conduct during its reverse bias. This is known as rectification, as it allows current to flow in one direction only. The current then follows the path of least resistance, which is from the AC source, through the diode, and through the load, before returning to the AC source.

Application Fieldof VS-1N2128RA

The VS-1N2128RA is suitable for use in high-frequency electrical power transmission applications due to its high breakdown voltage and high-frequency operation capabilities. It is also suitable for use in rectified AC current for a voltage-boosting transformer and rectified DC current for a DC power supply or switch-mode power supply applications. The VS-1N2128RA is ideal for applications where high-frequency operation and high voltage capability are required. It is also suitable for applications where a low leakage current and low forward voltage drop are desired.
