Panasonic MA3J745 Datasheet
Schottky Barrier Diodes (SBD)
MA3J745
Silicon epitaxial planar type
For switching circuits
■ Features
•
Optimum for low-voltage rectification because of its low forward
rise voltage (V
•
Optimum for high-frequency rectification because of its short
reverse recovery time (t
■ Absolute Maximum Ratings Ta = 25°C

Note) 1. Schottky barrier diode 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.
