reverse voltage การใช้

• The electric field grows as the reverse voltage increases.
• It will also provide a maximum reverse voltage limited by zener or avalanche breakdown.
• The breakdown starts when reverse voltage is applied.
• Reverse voltage or ripple currents higher than specified can destroy the dielectric and thus the capacitor.
• Two LEDs can be paired this way, so that each protects the other from reverse voltage.
• Nevertheless, electrolytic capacitors can withstand for short instants a reverse voltage for a limited number of cycles.
• Nevertheless, they can withstand for short instants a type dependent reverse voltage for a limited number of cycles.
• As pulse discharge capacitors, they are useful in applications with reversing voltages, such as in magnetizing equipment.
• This is different from a Zener diode, which will stop conducting once the reverse voltage drops below the breakdown voltage.
• While higher reverse voltages are achievable, they would present a higher forward voltage, comparable to other types of standard diodes.
• Most LEDs have low reverse breakdown voltage ratings, so they will also be damaged by an applied reverse voltage above this threshold.
• At the middle of the junction of the p n material, a depletion region is created to stand-off the reverse voltage.
• These guidelines apply for short excursion and should never be used to determine the maximum reverse voltage under which a capacitor can be used permanently.
• Since APD gain varies strongly with the applied reverse bias and temperature, it is necessary to control the reverse voltage to keep a stable gain.
• An even simpler model of the diode, sometimes used in switching applications, is short circuit for forward voltages and open circuit for reverse voltages.
• Peak repetitive reverse voltage is the maximum peak reverse voltage that may be applied continuously to the main terminals ( anode and cathode ) of quadracs.
• Peak repetitive reverse voltage is the maximum peak reverse voltage that may be applied continuously to the main terminals ( anode and cathode ) of quadracs.
• They are usually operated in discharge applications with non-reversing voltages, and at low repetition frequencies, such as in laser technology and lighting generators.
• On each of the alternate halves of the AC cycle, one anode acts as a blocking dielectric, preventing reverse voltage from damaging the opposite anode.
• The capacitance of a PN diode between anode and cathode is inversely proportional to the reverse voltage, growing as it approaches zero volts and into forward bias.
