A
Pin Assignment
This device has the lowest QRR of any 200 V
Silicon diode. Its recovery characteristics
increase efficiency, reduce EMI and eliminate
snubbers.
Applications
AC/DC and DC/DC output rectification
Output and freewheeling diodes
Motor drive circuits
DC-AC inverters

RoHS Compliant
Package uses Lead-free plating and “Green” mold
compound Halogen free per IEC 61249-2-21.
Low QRR, Low IRRM, Low tRR
High dIF/dt capable (1000A/s)
Soft recovery
Benefits
Increases efficiency
Eliminates need for snubber circuits
Reduces EMI filter component size and 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.

Note to component engineers: Q-Series diodes employ Schottky technologies in their design and construction.
Therefore, component engineers should plan their test setups to be similar to traditional Schottky test setups.
