Diode (noun)

An electronic component consisting of two terminals and a semiconductor material, used for rectification or as a detector or rectifier of an alternating current.

Origin:

Late 19th century: from dia- "across" + -ode, on the pattern of triode.

Examples:

1. The diode allowed current to flow in only one direction, protecting the circuit from damage.
2. The diode served as a simple switch, turning on and off in response to changes in voltage.
3. The diode was a key component in many electronic devices, such as radios and televisions.
4. The diode laser was used for a variety of applications, including surgery and data storage.
5. The diode characteristic curve showed the relationship between the voltage and current in the diode.
