# What is meant by PIV of a diode?

**Definition**.

**Peak Inverse Voltage**(

**PIV**) or Peak Reverse Voltage (PRV) refer to the maximum voltage a

**diode**or other device can withstand in the reverse-biased direction before breakdown. Also may be called Reverse Breakdown Voltage.

### What is the value of the peak inverse voltage on the diode in full wave rectifier?

This is in case of

**full wave**center tap**rectifier**.**Peak inverse voltage**(PIV) is the maximum possible**voltage**across a diode when it is reversed-biased. During first half-cycle of the supply i.e. when the top of the transformer secondary winding is positive, diode D1 conducts and offers almost zero resistance.#### What is the PIV rating of diode in bridge rectifier?

**PIV**(**peak inverse voltage**) of**Bridge Rectifier**.**PIV**: For**rectifiers**,**Peak inverse voltage**(**PIV**) or peak reverse voltage(PRV) can be defined as the maximum value of the reverse voltage of a**diode**, which occurs at the peak of the input cycle when the**diode**is in reverse bias.#### What is the efficiency of full bridge rectifier?

RMS value of the voltage at the load resistance is.**Efficiency**.**Efficiency**, h is the ratio of the dc output power to ac input power. The maximum**efficiency**of a Full Wave**Rectifier**is 81.2%.#### What is peak inverse voltage of a pn junction diode?

For rectifier applications,**peak inverse voltage**(PIV) or**peak**reverse**voltage**(PRV) is the maximum value of reverse**voltage**which occurs at the**peak**of the input cycle when the**diode**is reverse-biased. The portion of the sinusoidal waveform which repeats or duplicates itself is known as the cycle.

B.

### What is surge current of diode?

Maximum (peak or

**surge**) forward**current**= IFSM or if(**surge**), the maximum peak amount of**current**the**diode**is able to conduct in forward bias mode.#### What is the diode equation?

n is the ideality factor, also known as the quality factor or sometimes emission coefficient. The**equation**is called the Shockley ideal**diode equation**when n, the ideality factor, is set equal to 1.#### What is meant by blocking voltage?

**Blocking voltage**, BVDSS, is the maximum**voltage**that can be applied to the MOSFET. When driving an inductive load, this includes the applied**voltage**plus any inductively induced**voltage**. With inductive loads, the**voltage**across the MOSFET can actually be twice the applied**voltage**.#### What is the peak inverse voltage?

Definition.**Peak Inverse Voltage**(PIV) or**Peak Reverse Voltage**(PRV) refer to the maximum**voltage**a diode or other device can withstand in the**reverse**-biased direction before breakdown. Also may be called**Reverse**Breakdown**Voltage**.

C.

### What is the importance of the peak inverse voltage?

PIV is the maximum

**peak voltage**that a diode can withstand in the reverse non-conducting region. By withstand, it means that, upto this**voltage**the diode blocks conduction of current in the reverse direction.#### What do you mean by Ripple?

**Ripple factor**(γ) may be defined as the ratio of the root**mean**square (rms) value of the**ripple**voltage to the absolute value of the DC component of the output voltage, usually expressed as a percentage. However,**ripple**voltage is also commonly expressed as the peak-to-peak value.#### What is a reverse breakdown voltage?

The**breakdown voltage**of an insulator is the minimum**voltage**that causes a portion of an insulator to become electrically conductive. For diodes, the**breakdown voltage**is the minimum**reverse voltage**that makes the diode conduct appreciably in**reverse**.#### What do you mean by reverse saturation current?

In a PN junction diode, the**reverse saturation current**is due to the diffusive flow of minority electrons from the p-side to the n-side and the minority holes from the n-side to the p-side. The is flows in the**reverse**bias condition of the diode is called**reverse saturation current**.
