**Ultrafast Recovery Rectifier DUR6040WT, 2x 30A, 400V, TO-247AD, Common Cathode** 

## DUR6040WT 

## ~~**RoHS Pb e3** L100~~ 

## **Description** 

Littelfuse DUR series Ultrafast Recovery Rectifier is designed to meet the general requirements of commercial applications by providing low Trr, high-temperature, lowleakage and low forward voltage drop products. It is suitable for output rectifier, free-wheeling or boost diode in high-frequency power switching application such as switch mode power supply and DC-DC converters. 

## **Features** 

- Ultra-fast switching 

- Low reverse leakage current 

- High surge current capability 

- Low forward voltage drop 

- Common Cathode configuration in TO-247AD package 

- Pb-free E3 means 2nd level interconnect is Pbfree and the terminal finish material is tin(Sn) (IPC/ JEDEC J-STD-609A.01)
