The letter used is called a Reference Designation, and for a diode sometimes depends on what kind of diode it is. Most diodes use the letter D, as in D1, D2, D3. Zener diodes usually use the letter Z or much more rarely ZR or ZD (Zener Rectifier or Zener Diode). CR is an archaic designation that stands for Crystal Rectifier.
LEDs may use LED1, LED2, etc. or just D1, D2, etc.
A bridge rectifier (four diodes connected so AC fed into two leads results in pulsating DC from two other leads) uses BR for obvious reasons.

The letter symbol for the diode is D.

What is symbols of zener diode?
Usual symbol for diode is with a triangle - looking as an arrow hinged with a vertical line. Arrow head stands for anode for diode and line stands for its cathode. To give the symbol for zener diode we simply replace the vertical line by letter Z which also symbolizes the first designer 'Zener'
What is the symbol for a thyristor?
It is a standard diode, with an additional line leaving the cathode (- side) for the gate. See wikipedia link.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
The triangle in a diode symbol points in the direction of?
it points in the direction of flowing current due to majority carriers... that is from positive side to negative side
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the symbol for a light emitting diode?
The same as the standard symbol for a diode but with a lightning bolt shaped arrow pointing away from it added.
What is the symbol for diode?
The symbol for a diode is a horizontal line with an arrow pointing to an intersecting vertical line, the horizontal line continues on the other side of the vertical line.
Where gunn diode is used?
Gunn diodes are used in GUNN oscillator over high frequency application. its work on the transfer electron effect TET and the scientist J.B Gunn observe it so the phenomenon is named by gunn effect. the diode are made from GaAs material.because silicon is not suitable low forbidden energy gap 1.21eV only.
What is symbols of zener diode?
Usual symbol for diode is with a triangle - looking as an arrow hinged with a vertical line. Arrow head stands for anode for diode and line stands for its cathode. To give the symbol for zener diode we simply replace the vertical line by letter Z which also symbolizes the first designer 'Zener'
What is the symbol of esaki diode?
The symbol for the esaki diode, also known as the tunnel diode, is similar to the zener diode, except that the two stems on the end of the cathode both point back towards the anode, and they are at 90 degrees instead of 45 degrees. For more information, and a picture, please see the related link below.
Why not use and symbol in string function?
You shouldn't use it because it is not and gate in diode logic.
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
What does the symbol for a diode look like?
Diode symbols look like open triangles with horizontal lines extending from either side. There will be a vertical line at the tip of the triangle that may have turned ends depending upon the type of diode.
What is the symbol for a thyristor?
It is a standard diode, with an additional line leaving the cathode (- side) for the gate. See wikipedia link.
In the schematic symbol for a semiconductor diode the arrowhead represents?
The Anode. Think of the arrow like a Capital Letter A standing for the Anode.
What is the circuit symbol for a LED?
The symbol for the element lead is Pb. It stands for plumbum, the Latin name for the element lead.
