MA3X748 (MA748)
Silicon epitaxial planar type
For high frequency rectification
■ Features
• Low V
F
type of MA3X720 (MA720)
• Low forward voltage V

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 400 MHz.
