A DIAC is a diode alternating current switch. Its construction consists of two back to back diodes. It is usually used for triggering TRIACS.
What else can I help you with?
Difference between diac and triac?
The diac and the triac are used to control the AC lines. The difference is that triac are bigger than diac.
What is a DIAC?
Diac is a bidirectional electronic switch that can pass current in either directions according to the polarity applied on it.
Circuit diagram of illumination controller using diac and triac?
a circuit diagram consist of diac&triac
Can a diac trigger scr?
No, a Diac cannot trigger an SCR because when the Diac turns ON, the current through the Diac is around 9 mA. The gate threshold current of an SCR is typically 5 mA, which is less. So the SCR can get damaged due to this high gate current.
Can you equivalent the DIAC and comment?
A DIAC is a full-wave or bi-directional semiconductor switch that can be turned on in both forward and reverse polarities.
Can DIAC be replaced by two anti-parallel diodes?
i think not.diodes have a low breakdown voltage, around 1v. a diac has bv of about 30v.
A diac is equivalent to a?
pair of for layer of SCRS
Give the name of termials of DIAC?
Did I Act Crazy
What is the Full form of DIAC?
diode for alternating current
What is the advantages of DIAC in electronic devices?
it help student study better
When the DIAC turns on, the drop voltage will be decrease, why?
Less than consumption of
Can you use Diac and Triac for dc supply?
The diac conducts in both directions at approximately the same voltage, making it unsuitable in an AC to DC supply. The triac also conducts in both directions, based on a gate voltage which is slightly different in the two usable quadrants. That is why the diac is often used to trigger the triac - it makes the two conduction cycles more symmetric. In both cases, the diac/triac does not make sense for an AC to DC supply, but it works well in an AC voltage regulator, such as a lamp dimmer or motor speed controller.
