Panasonic MA3X748, MA748 User Manual
Schottky Barrier Diodes (SBD)
This product complies with the RoHS Directive (EU 2002/95/EC).
MA3X748 (MA748)
Silicon epitaxial planar type
For high frequency rectification
■ Features
• Low VF type of MA3X720 (MA720)
• Low forward voltage V
• Optimum for high frequency rectification because of its short
reverse recovery time t
■ 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 400 MHz.
