(electronics) An electronic device that allows current to flow in one direction only; used chiefly as a rectifier.

plural of diode

(physics) A semiconductor rectifying device in which the barrier between the two regions of opposite conductivity (n-type and p-type) type produces the rectification. All solar cells are junction diodes.

(physics) A metal-semiconductor diode that exhibits a nonlinear voltage/current relationship

(physics) A semiconductor diode that has negative resistance in the forward direction of its operating range due to quantum effects.

(electronics) A semiconductor junction device through which current flows normally in the forward direction, and in the reverse direction if a large voltage is applied.

(physics) A laser whose active medium is a form of light-emitting diode

plural of laser diode

plural of junction diode

plural of Zener diode
