• For high-efficiency power conversion in solar inverters, power supplies, and telecom applications.
• In other power electronics applications.

Working Principle

The basic working principle of rectifier diodes like the VS-50PFR40 is rectification. It allows current to flow in one direction only, from the anode to the cathode. This process is known as rectification - when an AC voltage is applied to the anode and the cathode, it will only allow current to flow during the forward half cycles. During the reverse half cycles, the diode is reversed biased and no current will flow through it.

When rectification occurs, the current flow is converted into a unidirectional DC voltage across the diode’s anode and cathode. This will help to eliminate any undesirable AC component or ripple in the output. The VS-50PFR40 is capable of blocking up to 50A and has a peak reverse voltage of 40V.

Key Features
