This section provides overview, applications, and principles of small signal diodes. Also, please take a look at the list of 2 small signal diode manufacturers and their company rankings.
A small signal diode is a diode that operates with a current as small as 200mA. Small signal diode is used for rectification to convert alternating current to direct current, switching, and generating constant voltage. They are also used to extract audio signals from radio waves. Radio waves, which are emitted by combining high-frequency signals with low-frequency audio signals, are transported as audio signals to audio output devices by utilizing the diode's property of detecting only low-frequency signals.
Small signal diodes are used in electrical equipment, precision instruments, radio receivers, and other products that operate using small signals. When selecting small signal diodes, the rated current and voltage must be carefully selected because of the increased potential for danger and failure. If there is a possibility of excessive current flow, a protection circuit should be installed to prevent excessive current flow to the diode.
The operating principle of small signal diodes are explained in terms of their typical functions: switching, rectification, and constant voltage generation.
