  • Specialized
translation icon : diodo semiconductor
  • A semiconductor diode is essential for converting alternating current into direct current in electronic circuits.

Examples

  • Instantaneously, the positive and negative electrical charges redistribute, establishing internal electric fields that determine, in part, the properties of the semiconductor diode.

    Academic text (1993)
  • The engineer explained how the semiconductor diode allows current to flow in only one direction.

  • In the lab, we tested the efficiency of the semiconductor diode by measuring its response to different voltage levels.

Morphology

semiconductor + diode

The meaning is directly and transparently derived from 'semiconductor' (a material with intermediate conductivity) and 'diode' (a device allowing current one way): it is simply a diode made from semiconductor material. This noun–noun compounding follows regular technical naming patterns and is cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

Semiconductor diode comes from its parts: a semiconductor is a material that only partly lets electricity through, and a diode is a device that lets electricity go in one direction. So, imagine a small one-way gate for electric current made from that special material, and that is why a semiconductor diode means 'a device that allows current to flow in one direction only'.
