Schottky Barrier Diodes (SBD)
MA4X746
Silicon epitaxial planar type
Unit : mm
For super-high speed switching circuit
For small current rectification
I
Features
•
I
F(AV)
= 200 mA, and V
R
> 50 V is achieved
•
Allowing automatic insertion with the emboss taping
•
Optimum for high-frequency rectification because of its short
reverse recovery time (t
rr
)
•
High rectification efficiency caused by its low forward-rise-
voltage (V
F
)

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.
