HiPerDynFRED
TM
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 I
RM
-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 I
RM
reduces:
- Power dissipation within the diode
- Turn-on loss in the commutating
switch
