**Ultrafast Recovery Rectifier DURB1640CT, 2x 8A, 400V, TO-263, Common Cathode** 

## DURB1640CT 

## ~~**RoHS Pb e3** LIOO~~ 

## **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** 

   - configuration in surface mount TO-263 (D[2] PAK) package 

- Ultra-fast switching 

- Low reverse leakage current 

- Pb-free E3 means 2nd 

- •   High surge current level interconnect is Pb- 

- capability free and the terminal finish 

- •   Low forward voltage drop material is tin(Sn) (IPC/ JEDEC J-STD-609A.01) 

- Common cathode
