1N5822 40V 3A schottky rectifier diode for use in low voltage
A Schottky diode, similar to a regular diode, limits the flow of
electricity to one direction, much like the action of a one-way
water valve. The Schottky diode, however, has an enhanced
electrical response time because of a much lower voltage
dissipation. Common malfunctions of a Schottky diode include
electrical shorting and overheating.
The semiconductor composition of a Schottky diode is slightly
different from a normal diode, and this results in a much smaller
forward voltage drop, which is usually between 0.15V and 0.45V.
They’ll still have a very large breakdown voltage though.
Schottky diodes are especially useful in limiting losses, when
every last bit of voltage must be spared. They’re unique enough to
get a circuit symbol of their own, with a couple bends on the end
of the cathode-line.
