HiPerFREDTM Epitaxial Diode

with soft recovery

Features

●

International standard package
miniBLOC

●

Isolation voltage 2500 V~

●

UL registered E 72873

●

2 independent FRED in 1 package

●

Planar passivated chips

●

Very short recovery time

●

Extremely low switching losses

●

Low IRM-values

●

Soft recovery behaviour

Applications

●

Antiparallel diode for high frequency
switching devices

●

Antisaturation diode

●

Snubber diode

●

Free wheeling diode in converters
and motor control circuits

●

Rectifiers in switch mode power
supplies (SMPS)

●

Inductive heating

●

Uninterruptible power supplies (UPS)

●

Ultrasonic cleaners and welders

Advantages

●

Avalanche voltage rated for reliable
operation

●

Soft reverse recovery for low
EMI/RFI

●

Low IRM reduces:

- Power dissipation within the diode

- Turn-on loss in the commutating
switch
