SKH00087CED

(MA787)

Silicon epitaxial planar type

For super high speed switching

For small current rectification

■ Features

• Forward current (Average) I

F(AV)

 

= 100 mA rectification is

possible

• Optimum for high frequency rectification because of its short

reverse recovery time t

rr

• Low forward voltage V

F

 and good rectification efficiency

• Reverse voltage V

R

 

= 50 V is guaranteed

■ Absolute Maximum Ratings  T

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 200 MHz.
