Description
The MBR3100 is a high voltage Schottky rectifier suited for switch
mode power supplies and other power converters. This device is
intended for use in medium voltage operation, and particularly, in high
frequency circuits where low switching losses and low noise are
required.
The MBR3100 is available in standard DO-214AC and DO-27
packages.

Maximum Ratings (Note 5)
Notes: 5. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied.
Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.
6. The heat generated must be less than the thermal conductivity from Junction to Ambient: dPD/dTJ < 1/θJA.
