Question

What is the symbol of a pn junction diode?

Answer 1

The symbol of a PN junction diode consists of a triangle pointing towards a vertical line.

Here’s a breakdown of the symbol:

1. The triangle represents the anode (P-type side).
   

1. The vertical line represents the cathode (N-type side).
   

1. The arrowhead shows the conventional current flow direction (from P to N when forward biased).
   

PN Junction Diode Symbol:

`
   Anode (+)       Cathode (-)
       |               |
       |—|>|—|
       |               |
`

This symbol visually indicates that current flows only in one direction, from the anode (P) to the cathode (N), when the diode is forward biased.
