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
• Easy to mount with two screws
• Space and weight savings
• Improved temperature and power
cycling capability
• Low noise switching
• Small and light weight
