FEATURES
DESCRIPTION
• Low forward voltage
Planar Schottky barrier diode with an
integrated protection ring against
static discharges.
This surface mounted diode is
• High breakdown voltage
• Guard ring protected
• Hermetically-sealed small SMD
package.
APPLICATIONS
k
handbook, halfpage
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.
a
• Ultra high-speed switching
• Voltage clamping
• Protection circuits
MAM190
• Blocking diodes.

DEFINITIONS
Data sheet status
Objective specification
This data sheet contains target or goal specifications for product development.
Preliminary specification
This data sheet contains preliminary data; supplementary data may be published later.
Product specification
This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
