Schottky Barrier Diodes (SBD)
MA4X714
Silicon epitaxial planar type
For switching circuits
For wave detection circuit
I Features
Two MA3X704As are contained in one package (Two diodes in a
different direction)
Optimum for low-voltage rectification because of its low forward
rise voltage (V
F
)
Optimum for high-frequency rectification because of its short re-
verse recovery time (t
rr
)

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
2. Rated input/output frequency: 2 000 MHz
