1N5822 40V 3A schottky rectifier diode for use in low voltage
Description:
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.
Features:
• Extremely low VF
• Epitaxial construction
• Low power loss, high efficiency
• Low stored charge, majority carrier construction
• Plastic material has UL flammability classification 94V-0
Application:
• Schottky diodes are used as general-purpose rectifiers.
• Schottky diodes are used in radio frequency (RF) applications.
• Schottky diodes are widely used in power supplies.
• Schottky diodes are used to detect signals.
• Schottky diodes are used in logic circuits.
