FEATURES
Low forward voltage
High breakdown voltage
Guard ring protected
Hermetically-sealed small SMD
package
Low diode capacitance.
APPLICATIONS
Ultra high-speed switching
Voltage clamping
Protection circuits
Blocking diodes.
DESCRIPTION
Planar Schottky barrier diode with an
integrated protection ring against
static discharges. This surface
mounted diode is encapsulated in a
hermetically sealed SOD80C glass
SMD package with tin-plated metal
discs at each end. It is suitable for
"automatic placement" and as such it
can withstand immersion soldering.
