when a semiconductor is doped with p-type and n-type impurities, a pn junction is formed which acts as a diode and prevents the charge carriers to flow to either side of junction
pn juction diode is a semiconductor device that allows current to flow only to one direction.

∙ 12y agoWhen the diode is reversed biased (positive charge applied to the N side and the negative charge applied to the P side) no current can flow just like when a switch is off. When the diode is forward biased (positive charge applied to the P side and the negative charge applied to the N side) no current can flow just like when a switch is on. Current can only flow in one direction.

Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
Can diode work as switch?
yes diode can be used as a switch as it conducts current in only one direction.it is a open switch when it reverse biased.and as aclosed switch when it is forward biased.but we consider diode as ideal .
What is similar to diode operation?
switch is similar to diode action
When biased correctly a zener diode acts as?
a diode and it has a constant voltage across it ANSWER: acts as a voltage regulator if enough current flows to create a breakdown voltage.
Will bad diodes work?
A failed diode electrically resembles a switch. Whether it resembles an open switch or a closed one depends on the specific mode in which it failed. But a bad diode won't behave like a diode any more.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
What is a device made of semiconductor material that acts like a switch controlling the flow of electrons in a chip?
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
Can Crystal Diode acts as a Automatic Switch?
A diode typically has low resistance for current in one direction, and high resistance for current in the other direction. This is not really the description of anything that could be called a 'switch'.
How does a PN junction diode acts as a switch?
A diode is voltage and current sensitive it follows an exponential curve and lower then .6v it is considered off and above .6v is considered on.
What is use of diode?
Diode is a two terminal semicon. Diode is a Switching device
Can diode work as switch?
yes diode can be used as a switch as it conducts current in only one direction.it is a open switch when it reverse biased.and as aclosed switch when it is forward biased.but we consider diode as ideal .

switch is similar to diode action
How does diode acts as a switch?
When the diode is reversed biased (positive charge applied to the N side and the negative charge applied to the P side) no current can flow just like when a switch is off. When the diode is forward biased (positive charge applied to the P side and the negative charge applied to the N side) no current can flow just like when a switch is on. Current can only flow in one direction.
What is the purpose of a diodes in a circuit?
a diode in a ckt basically acts like a switch!! it acts like a switch in on position i.e a short when forward biased and acts like a open ckt or a swich in off position when it is reversed biased!! its used inanalog circuits to generate different types of waves.........
How does a p-n junction diode work as a switch?
diode conducts in forward bias.so it is on switch. in reveres bias it will not conduct.so it is off switch
How diode can be used as switch?
No, a diode can rectify an AC signal but is not able to amplify an AC signal. Diodes are two layer devices whereas transistors have three. It is this very thin 'base' region in the transistor that gives it the ability to give a voltage or current gain.
What is use of the diode?
The use of the pn diode is for rectification. It can also be used as a switch.
