Publication date: April 2004 SKH00087CED
MA3X787 (MA787)
Silicon epitaxial planar type
For super high speed switching
For small current rectification
■Features
•Forward current (Average) IF(AV) = 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
•Reverse voltage VR = 50 V is guaranteed
■Absolute Maximum Ratings Ta = 25°C
Marking Symbol: M3U

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 200 MHz.
4.*: trr measurement circuit
Note) *: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.
This product complies with the RoHS Directive (EU 2002/95/EC).
