Switch and Diode: definition (structure)

Definition

A switch and diode components are defined by:

  • a name (and a comment)
  • a model
  • specific characteristics depending on the model
  • a command
  • two terminals

Name

The name permitting the identification of the component is given by the user when this is created by him.

A comment (optional) can be added to the name.

The name and the comment are displayed by default in the graphic zone close to the symbol.

Switch and Diode: description

Characteristic quantities, necessary for the description of the switch and diode components are presented in the table below.
