- The diode is destroyed
- The diode behaves like a capacitor
If the PIV rating of a diode is exceeded, the diode is destroyed. The greatest reverse voltage that a PN-junction (or diode) can withstand without being damaged is known as a diode’s peak inverse voltage rating (or destruction). It refers to a diode’s peak inverse voltage rating (PIV). A diode is likely to experience a breakdown at the junction and be damaged if the applied voltage is greater than PIV.
Peak Inverse Voltage
Peak Inverse Voltage is referred to as PIV. The highest reverse bias voltage that a semiconductor diode or other semiconductor devices can withstand without suffering self-damage is referred to as this. Peak reverse voltage is another name for the peak inverse voltage.
Temperature affects a diode’s PIV rating. It grows when the temperature rises and shrinks when the temperature falls. Manufacturers determine peak inverse voltage ratings. At room temperature, a common rectifier diode has a PIV value of at least 50Vdc. However, there are also diodes on the market with high peak inverse voltage ratings of thousands of volts.
Summary:
If the PIV rating of a diode is exceeded, ________. (a) The diode conducts poorly (b) The diode behaves like a tunnel diode (c) The diode is destroyed (d) The diode behaves like a capacitor.
A diode is damaged when its PIV rating is surpassed. The highest reverse voltage which a PN junction can withstand without damage is called the peak inverse voltage range of a diode
