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.

Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
What is difference between power diode and ordinary diode?
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
What are the difference between Ge and Si diode?
the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev
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.
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 the difference between a DIAC and a TRIAC?
A DIAC is simply a diode that breaks down at predictable voltage.A TRIAC is a 3 terminal device that will conduct whether the anode is at a positive or a negative potential, controlled by a gate.Another answerThey are AC versions of the SCR and diode respectively. Do you need more details?
What is the Full form of DIAC?
diode for alternating current
What is the difference between detector and diode detector?
difference between detector and diode
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 difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
Reverse characteristics graph of pn junction diode?
what is the difference between reverse characteristics of zener diode and a practical diode ?
What is difference between a diode and a photo diode?
diodediode conducts by applying certain voltagephoto diodephoto diode conducts when it is exposed to sun light
What is the difference between potentiometer and light-sensitive diode?
potentiometer is not sensitive to lightpotentiometer has three terminals, diode has two
What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
