Schottky Barrier Diodes (SBD)
1
Publication date: February 2005 SKH00090DEDMA3X791 (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 IF = 100 mA rectification is possible
•Optimum for high frequency rectification because of its short
reverse recovery time trr
•Low forward voltage VF and good rectification efficiency
■Absolute Maximum Ratings Ta = 25°C

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 bodyand the leakage of current from the operating equipment.3.Absolute frequency of input and output is 250 MHz.4. *: trr measurement circuitNote) *1:Value of each diode in series diodes used.*2:The peak-to-peak value in one cycle of 50 Hz sine wave (non-repetitive)Note) The part number in the parenthesis shows conventional part number.
