VS-VSKE236/04PBF

Diodes - Rectifiers - Single

The VS-VSKE236/04PBF part is a diode rectifier and is classified in the family of single rectifiers. It is specifically suited for high frequency switching mode power supply circuits, where low forward voltage drop and fast reverse recovery time are the main requirements. It has a repetitive peak reverse voltage rating of 600V and a DC forward current rating of 11A. Let’s take a closer look at the application field and working principle.

Application Field

The VS-VSKE236/04PBF is designed primarily as an efficient and fast switching mode rectifier. It works well in SMPS (switch-mode power supply) circuits, allowing for high-frequency switching operations and higher efficiencies than traditional linear power supplies. In addition, this part can be used for most full-wave AC-DC rectification applications and has a peak repetitive reverse voltage rating. It can also find applications in high-operation frequency, low voltage/high speed rectification applications, such as telecommunications, battery charging equipment, household appliances, etc.

Working Principle

The VS-VSKE236/04PBF is a single, epitaxial-base, fast recovery-type rectifier. It combines fast switching and low forward voltage drop characteristics. The anode is connected to a thickened top aluminum metal layer while the cathode is connected to a heavily doped semiconductor layer. When a current is passing through the part in forward mode (anode to cathode), the semiconductor becomes active and forward current flow is enabled. When the current is reversed, the diode enters the reverse mode and becomes non-conductive. During this process, the fast recovery time characteristic of this part ensures a fast, high current load switch.

Conclusion

The VS-VSKE236/04PBF is an efficient, small-signal, single rectifier. It is perfectly suited for high frequency operations, SMPS circuits and low voltage/high speed rectification applications. Thanks to its fast recovery characteristics, it can be used in most full-wave AC-DC rectification applications.
