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

∙ 14y agoThe 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 PIV rating is required for the diodes in a bridge rectifier that produces an average output voltage of 50 V?
Its 50-0.7=49.3V Using this Formula : PIV Rating = Vout - 0.7V
What are the limiting values of a PN junction Diode?
A: heat And PIV(Peak Inverse Voltage) or so called Peak Reverse Voltage is limit the diode characteristics.
How do you calculate PIV?
PIV=Vm*2 where Vm is the peak vlaue voltage
Why maximum forward current is important rating of a diode?
if you exceed the max forward current the depletion region will become too small and will no longer allow any voltage through. it will also cause the diode to begin breaking down and will result in the death of the component.
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 PIV.Why PIV of a semiconductor diode is important?
peak inverse voltage... piv of semiconductor is impoetant bcz we need to know after a peak voltage the diode get breakdown or damaged... so we need to know the peak voltage. piv is a point which withstands the maximum reverse biased voltage. after which the diode get damaged.
The PIV of a diode is considered only when it is used as a rectifier?
A: Absolutely not. Any application of a design will have a minimum PIV for the circuit
What is PIV in electronics?
The Peak inverse voltage (PIV) equals the peak value of the input voltage, and the diode must be capable of withstanding this amount of repetition reverse voltage. For the diode in figure, the maximum value of reverse voltage, designated as PIV, occurs at peak of each positive alternation of the input voltage when the diode is forward biased.Peak Inverse Voltage at Positive Half CycleThe Peak Inverse Voltage (PIV) occurs at the peak of each half-cycle of the input voltage when the diode is forward biased . In this circuit, the PIV occurs at the peak of each positive half cycle.
What happens to the diode if it has high piv?
It can be connected in high reverse bias voltage .
How does a diode shorted?
due to high voltage across the diode ie more than piv of the diode or current flows more than maximum allowed range of diode.
What will happen if a voltpage more than PIV rating of diode is applied across the diode?
peak inverse voltage :- it is the maximum voltage above which if applied the diode gets destroyed. Here destroyed in the sense the p-n junction gets destroyed due to breakdown voltage, it behaves like a straight conducting wire (which is of no use).
What PIV rating is required for the diodes in a bridge rectifier that produces an average output voltage of 50 V?
Its 50-0.7=49.3V Using this Formula : PIV Rating = Vout - 0.7V
What are the limiting values of a PN junction Diode?
A: heat And PIV(Peak Inverse Voltage) or so called Peak Reverse Voltage is limit the diode characteristics.
What is PIV value of a half wave rectifier?
A: It realy does not matter half or full wave. the PIV will be 1.41 the RMS input example 100v ac will have a requirement of PIV of 141 volts on the rectifiers.
4. To more accurately represent a diode what factors must be included?
1. At what point on the input cycle does the PIV occur?
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.
