RoHS Compliant
Package uses Lead-free plating and Green mold
compound.Halogen free per IEC 61249-2-21.
General Description
This device has the lowest QRR of any 300 V
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 QRR, Low IRRM, Low tRR
• High dIF/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.
