This product complies with the RoHS Directive (EU 2002/95/EC).
MA3J745EG
Silicon epitaxial planar type
For high speed switching
For wave detection
Features
Two elements are contained in one package, allowing highdensity
mounting
Low forward voltage VF , optimum for low voltage rectication
Optimum for high frequency rectication because of its short
reverse recovery time trr
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 body and the leakage
of current from the operating equipment.
3. Absolute frequency of input and output is 2 GHz
