What is a DIAC?
Diac is a bidirectional electronic switch that can pass current in either directions according to the polarity applied on it.
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.
What is the name of the scr or triac triggering system that triggers the output device at the same point on each ac cycle?
Diac
What is the difference between diac and diode?
A diode is a component that lets current flow in only one direction. A zener diode has an additional property that current will begin to flow in the reverse direction when a reverse voltage is applied above a certain threshold. This property is generally used for voltage regulation purposes. A diac has similar voltage regulating properties but behaves the same in both directions - current will flow through it when a voltage above it's threshold voltage is applied in either direction. It is therefore useful in AC as well as DC circuits. Below the threshold voltage the diac will be off - no current will flow. A diac is electrically similar to a neon bulb or gas regulator tube.
Why diac should be tested with power supply and cannot be tested with digital multimeter?
It's like a spark plug, it needs higher voltage to transmit the power.
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.

Circuit diagram of illumination controller using diac and triac?
a circuit diagram consist of diac&triac

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.
What is the name of the scr or triac triggering system that triggers the output device at the same point on each ac cycle?
Diac
A diac is equivalent to a?
pair of for layer of SCRS
What is function of DIAC?
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 is the Full form of DIAC?
diode for alternating current
How do I reset the computer in my 2004 range rover?
disconnnect battery termials, wait 10 minutes, touch the terminals together, reconnect
What is the advantages of DIAC in electronic devices?
it help student study better
