Publication date: February 2005 SKH00090DED
MA3X791 (MA791)
Silicon epitaxial planar type
For super high speed switching
For small current rectification
■ Features
• Two MA3X786 (MA786) is contained in one package (series
connection)
• Forward current I
F
= 100 mA rectification is possible
• Optimum for high frequency rectification because of its short
reverse recovery time t
rr
• Low forward voltage V
F
and good rectification efficiency

Note) 1. Measuring methods are based on JAPANESE INDUSTRIAL STANDARD JIS C 7031 measuring methods for diodes.
2. This product is sensitive to electric shock (static electricity, etc.). Due attention must be paid on the charge of a human body
and the leakage of current from the operating equipment.
3. Absolute frequency of input and output is 250 MHz.
