DIAC
The DIAC is a diode that conducts electrical current only after its breakover voltage, VBO, has been reached momentarily. The term is an acronym of diode for alternating current.
When breakdown occurs, the diode enters a region of negative dynamic resistance, leading to a decrease in the voltage drop across the diode and, usually, a sharp increase in current through the diode. The diode remains in conduction until the current through it drops below a value characteristic for the device, called the holding current, IH. Below this value, the diode switches back to its high-resistance, non-conducting state. This behavior is bidirectional, meaning typically the same for both directions of current.
Most DIACs have a three-layer structure with breakover voltage of approximately 30 V. Their behavior is similar to that of a neon lamp, but it can be more precisely controlled and takes place at a lower voltage.
DIACs have no gate electrode, unlike some other thyristors that they are commonly used to trigger, such as TRIACs. Some TRIACs, like Quadrac, contain a built-in DIAC in series with the TRIAC's gate terminal for this purpose.
Never Far Away
Everything I do Is all done for you
Lady I'm yours
And everywhere I go
You're always on my mind
You're all I adore
And I'll go
Outta my way
Just to assure
That our love endures I'm yours
Girl I'm never far away I'll be right there (right there)
To keep you nice and warm I'm rushing right home
Girl I'm never far away I'll be right there (right there)
To protect you from the storm I'm rushing right home
Girl I'll be there I'll be right there
I don't need you say
That I love you
A million times a day
Just the little things I do
All done for you
That's how I display
Love
And I'll go
Out of my way
Just to assure you baby
That our love endures I'm yours
Girl I'm never far away I'll be right there (right there)
To keep you nice and warm
(Girl I'll keep you nice and warm,
You know I'll keep you nice and warm
You know I'll keep you nice and warm)
Girl I'm never far away I'll be right there (I'll be right there)
To protect you from the storm I'm rushing right home
Girl I'll be there I'll be right there
You don't have to go and check my pager
Check my phone and search my pants to figure me out (ha)
Cause I'm an honest man
Don't need a plan, a stronger man
Cause girl there is no doubt
My love's real (as real as it comes)
Even though we are a million miles away from each other
I'm still right here, right here for you
(Here for you, here for you) I could search a million years
And still I wouldn't find anyone as beautiful as you
So rest assured our love endures I'm never far away...
