Fast Recovery
Epitaxial Diode (FRED)
Features
• International standard package
JEDEC TO-247 AD
• 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
• Anti saturation diode
• Snubber diode
• Free wheeling diode in converters
and motor control circuits
• Rectifiers in switch mode power
supplies (SMPS)
• Inductive heating and melting
• Uninterruptible power supplies (UPS)
• Ultrasonic cleaners and welders
Advantages
• High reliability circuit operation
• Low voltage peaks for reduced
protection circuits
• Low noise switching
• Low losses
• Operating at lower temperature or
space saving by reduced cooling
