Diodes are electrical components used to control the flow of electricity in a circuit. They are categorized into various types depending on their characteristics and applications. One category is rectifiers, which are used to convert alternating current (AC) to direct current (DC). The single type of rectifiers includes a single diode as the active device. This article will focus on the VS-12FR100M diode and its application field and working principle.

The VS-12FR100M is a single-phase silicon rectifier diode. It is designed for use in applications such as power supplies, UPS, and battery rectifiers. This diode is capable of passing 100A of forward current with a blocking voltage of 600 V (RMS). Its forward voltage drop is 1.75V at rated current. Manufacturer’s data gives a maximum junction temperature of 150°C.

As a rectifier device, the VS-12FR100M is used for rectification purposes. This is the process of transforming an AC voltage to DC voltage. In a half-wave rectification circuit, one of the two cycles is filtered out, leaving the other one unaltered. When the positive cycle of the AC voltage appears, the diode will conduct the current to the load; while the negative cycle of the AC voltage is blocked by the diode. In a full-wave rectification circuit, both the positive and the negative cycles of the AC voltage are rectified, while the average voltage value will remain unchanged. The diodes used in full-wave rectification need to be connected in a bridge configuration.

The working principle of the VS-12FR100M is based on the principle of the PN junction. This is an area of a semiconductor device which contains two varieties of silicon: a positive layer and a negatively charged layer. The junction between these two layers acts as a potential barrier and creates an electric field. When an electric potential is applied, the electrons are forced to cross the junction, resulting in a type of current flow, known as diode current.

The VS-12FR100M is a standard power rectifier that can be used in applications in many different fields, such as UPS, power supplies, and battery rectifiers. It is a low cost and reliable solution for rectification of AC voltages, due to its low forward Voltage drop and high current rating. Additionally, the diode features a temperature rating of up to 150°C, meaning it is suitable for use in high-temperature environments. This makes the VS-12FR100M a reliable and cost-effective solution for a wide range of rectification applications.
