**Ultrafast Recovery Rectifier DUR2030CT, 2x 10A, 300V, TO-220AB, Common Cathode** 

## DUR2030CT 

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

## **Description** ~~Po~~ 

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** [oo 

   - configuration in TO-220AB package 

- Ultra-fast switching 

- Low reverse leakage current • Pb-free E3 means 2nd level interconnect is 

- •   High surge current Pb-free and the terminal 

- capability finish material is tin(Sn) 

- •   Low forward voltage drop (IPC/JEDEC J-STD609A.01) 

- Common Cathode
