What it represents
A diode terminal includes a semiconductor diode in a documented terminal path. Polarity and the intended protective or decoupling function must remain explicit in the wiring schematic.
How to read it
- Read anode and cathode connections from the actual terminal diagram.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Mark diode direction
- Name terminal connections
- Reference voltage/current rating
A distinction that matters
A diode terminal is different from a feed-through terminal even if its physical housing is similar.
