Working Principle

The VS-70HFR40M is an anode-connected single diode rectifier. When a voltage is applied to the anode, electrons from the anode flow across the PN-junction and into the cathode, forming a current. The diode acts as a one-way valve for the electrons, allowing them to flow only in one direction. The forward recovery characteristics of the device are determined by the amount of time it takes for the electrons to re-establish equilibrium across the junction after the voltage is removed.

Conclusion

The VS-70HFR40M is a single diode rectifier with high forward recovery characteristics. It can operate up to 1000V and is suitable for a variety of applications such as switching power supplies, motor drives, UPS systems, DC-DC converters, and automotive applications. Its high forward recovery characteristics enable it to be used in high efficiency applications, and it is RoHS compliant and has a UL94V-0 rating.
