Electrical Symbols — Semiconductor

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance — higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics.

Semiconductor devices can display a range of useful properties such as passing current more easily in one direction than the other, showing variable resistance, and sensitivity to light or heat. Because the electrical properties of a semiconductor material can be modified by doping, or by the application of electrical fields or light, devices made from semiconductors can be used for amplification, switching, and energy conversion.

How to Create an Electrical Diagram Using Semiconductor Library

  • Open ConceptDraw DIAGRAM new document page.
  • Select libraries from Electrical Engineering section.

    Libraries from Electrical Engineering section

  • There are a few different ways to place an object into your drawing:

    • Click on an object and then click on the document, at the place you want the object to be inserted.
    • Perform a drag-and-drop from the library to your document.
    • Double click on an object’s icon in the library to place an object in the center of your document.
  • Select the Smart Connector tool Smart Connector. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
  • Result: Electrical Diagram.
