2Pin DO-214AA SMB Schottky Barrier Surface Mount Rectifier Diode
SS24 2.0A
I Surface Mount Rectifier Diode Description
These diodes exhibit very low forward voltage drop with a very fast
switching action. The reverse recovery times of Schottky diodes are
extremely short and they are suitable for applications requiring
fast switching and low power loss.
II Surface Mount Rectifier Diode Working of Schottky Diode
The most important physical parameter of this Schottky diode is
their fast switching rate and less forward voltage drop. It is a
metal – semiconductor junction that does not have the capacity to
store charges at their junction. The reason behind this is due to
absence of depletion layer.
Usually, a voltage drop happens across the diode terminals, when
current flows through a diode. Schottky diode voltage drop is
usually between 0.15 and 0.45 volts when compared to a normal
diode. A normal PN junction diode has a voltage drop ranging
between 0.6 to 1.7 volts. For a better efficiency and output,
voltage drop should be low. When manufacturing the diode, N-type
semiconductor acts as a cathode and the metal side acts an anode of
the diode.
When voltage is given to the diode, the current flows in the
forward direction. When this current flows through the diode, there
will be a minimum voltage loss across the terminals of the diode.
This loss of voltage is called as Voltage drop.

VI Surface Mount Rectifier Diode Applications of Schottky Diode
Schottky diodes are used in electronics industry for many
applications in diode rectifier because of its properties. They are
used for voltage clamping applications, to prevent transistor
saturation. It is used as Schottky TTL in digital devices as these
devices require fast switching. as the performance of digital
computers is determined by switching speed of diodes, Schottky
diode is an important component for digital computers.For use in
low voltage high frequency inverters, freewheeling, DC/DC
converters, and polarity protection applications.
