HiPerFREDTM Epitaxial Diode
with soft recovery
Features
●International standard package
●Planar passivated chips
●Very short recovery time
●Extremely low switching losses
●Low IRM-values
●Soft recovery behaviour
●Epoxy meets UL 94V-0
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
