Ultrafast Recovery Rectiﬁer

DUR30120, 30A, 1200V,TO-220AC

RoHS

DUR30120

Description

Littelfuse DUR series Ultrafast Recovery Rectiﬁer is

designed to meet the general requirements of commercial

applications by providing lowTrr, high-temperature, low-

leakage and low forward voltage drop products. It is suit-

able 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

• Single die in true two-

leadedTO-220AC

• Low reverse leakage

current

• Pb-free E3 means 2nd

level interconnect is Pb-

free and the terminal ﬁnish

material is tin(Sn) (IPC/

JEDEC J-STD-609A.01)

• High surge current

capability

• Low forward voltage drop

Applications

Circuit Diagram

• Output rectiﬁers in switch • Uninterruptible Power

mode power supplies

(SMPS) and DC to DC

converters

Supplies (UPS)

• Inductive heating and

melting

• Free-wheeling diode or

boost diode in converters

and motor control circuits

• Ultrasonic cleaners and

welders

Cathode

Anode

• Anti-parallel diode for

high frequency switching

devices such as IGBT
