Schottky Barrier Diodes Specification Sheet

Schottky Barrier Diodes (SBD)
1
Publication date: April 2004 SKH00107BED
MA4X746 (MA746)
Silicon epitaxial planar type
For super high speed switching
For small current rectification
■ Features
• Two isolated elements are contained in one package, allowing
high-density mounting
• Forward current (Average) I
F(AV)
= 200 mA and Reverse voltage
V
R
< 50 V are achieved
• Optimum for high frequency rectification because of its short
reverse recovery time t
rr
• Low forward voltage V
F
and good rectification efficiency

: Value of each diode in double diodes used.
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 1 GHz.
