General Description
This device has the lowest Q_RR of any 300V
Silicon diode. Its recovery characteristics
increase efficiency, reduce EMI and eliminate
snubbers.
Applications
• AC/DC and DC/DC output rectification
• Output & freewheeling diodes
• Motor drive circuits
• DC-AC inverters
Features
• Low Q_RR, Low I_RRM, Low t_RR
• High dI_F/dt capable (1000A/µs)
• Soft recovery
Benefits
• Increases efficiency
• Eliminates need for snubber circuits
• Reduces EMI filter component size & count
• Enables extremely fast switching
Absolute Maximum Ratings
Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
