What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
IN5408 diode what does it do?
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
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
Why current rating of diode is given but voltage rating is not given?
In the forward direction the effective resistance of the diode is essentially zero. By Ohm's Law Voltage = Current x Zero. However, in a reversed bias situation there is typically a breakdown voltage that could destroy the device or in some cases cause a reverse current to flow as part of the circuit design.
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.

What is the PIV rating of diode?
A diode will provide saturating current if it reaches its Piv. What it should be well at least 1.5 of the applied reverse voltage. For AC at least 2 times to insure that the peak REVERSE voltage is blocked
WHAT IS rectifiers 1N4007?
The 1N4007 is a diode with forward current rating of 1 ampere, and a reverse voltage rating of 1,000 volts.
Why current rating of diode is given but voltage rating is not given?
In the forward direction the effective resistance of the diode is essentially zero. By Ohm's Law Voltage = Current x Zero. However, in a reversed bias situation there is typically a breakdown voltage that could destroy the device or in some cases cause a reverse current to flow as part of the circuit design.
What are the amount of voltage across the diode?
The amount of (forward biased) voltage across a diode is dependent on current and temperature. A typical silicon diode has a forward voltage of about 0.6V at low current and temperature. As current goes up, voltage goes up slightly, with a typical voltage being 1.4V at high current. As temperature goes up, voltage goes down slightly, but the maximum current rating also goes down.
What is the significance of piv of diode?
The PIV (Peak Inverse Voltage) rating of a diode is the maximum voltage that you should apply to it in the reverse biased condition. Exceeding this voltage can destroy the diode.
What is the voltage rating of a 1ZB43BB zener diode?
43 Volts.
What is the condition that prevent the current to pass across diode?
if the voltage across the diode is less than the cut-in voltage of that particular diode .
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
