Littelfuse MBR series Schottky Barrier Rectifier is
designed to meet the general requirements of commercial
applications by providing high temperature, low leakage
and low V
F
products.
It is suitable for high frequency switching mode power
supply, free-wheeling diodes and polarity protection
diodes.
Features
• High junction
temperature capability
• Guard ring for enhanced
ruggedness and long
term reliability
• Low forward voltage drop
Applications
• High frequency operation
• Single die in true two-
leaded TO-220AC
package (no center pin)
