Working Principles

The VS-40HFLR100S05M is a rectifier diode that allows current to flow in only one direction, enabling efficient conversion of alternating current (AC) to direct current (DC). When a positive voltage is applied to the anode with respect to the cathode, the diode conducts, allowing current to flow. Conversely, when the voltage polarity is reversed, the diode blocks the current flow.

Detailed Application Field Plans

The VS-40HFLR100S05M is commonly used in power supply circuits, battery chargers, and motor drive applications where high current rectification is required. Its fast switching characteristics make it suitable for high-frequency applications such as switch-mode power supplies and inverters.
