The high surge current capability and low forward voltage of the UFS520JE3/TR13 also make it well-suited for use in high power applications, such as motor drives, welding equipment, UPSs and solar inverters where it is important to keep switching losses low.

Working Principle

UFS520JE3/TR13 rectifier diodes are based on a hybrid planar technology which provides low forward voltage drop, high surge current capability, and low reverse leakage current. The diode consists of an epitaxial diode layer (anode) and a PN junction (cathode) to form a single junction structure.

When the anode of the UFS520JE3/TR13 is positive with respect to the cathode, the diode is forward biased and allows current to flow. The electrical current is limited only by the resistance of the device, and the junction is made of low resistive material to enable high forward current flow.

When the anode is negative with respect to the cathode, the diode is reverse biased and no current flows. The UFS520JE3/TR13 has a reverse breakdown rating (VBR) of 200V and a reverse current rating (IR) of 0.2mA.
