The barrier potential of the silicon diode is 0.7v if the applied voltage across it is more than this voltage then PN-junction of the diode breaks, once pn-junction breaks the voltage across the diode is constant, since it breaks at 0.7 this voltage will be constant and not exceed for any further increase in applied voltage -inform.mayaprasad@gmail.com The voltage across junction will only exceed from 0.7 volt (for silicon diode) in the case of reverse biasing the applied total voltage will appear across p-n junction. ANSWER: .7 VOLTS is an arbitrarily chosen number since a diode any diode have an exponential curve V vs I . This number is chosen when using a diodes but there are times when a greater or lesser voltage is chosen to reflect the application and the current trough the diode determine that. Example a diode gate diode will be chosen as .6 volts rather then .7v and a heavy conducting rectifier may have .8 volt to reflect closely the true value of the diode drop during real conditions
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
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
If the coil is powered with DC voltage, an inductive voltage is created anytime power to the coil is de-energized. The inductive voltage is called an inductive kick and it is up to ten times the applied voltage and is in reverse polarity to the applied voltage. A diode or other type of suppression device must be connected across the coil of the solenoid to protect any other electronic components in the circuit that may be damaged by this voltage. The diode is connected in reverse bias across the DC solenoid coil so that when voltage is applied in normal polarity, the diode does not provide a path for current. When the solenoid coil is de-energized, the inductive voltage is the opposite polarity to the power supply, so it will flow through the diode and back into the coil. Since the coil is made of a large length of wire. the energy of the inductive voltage will be dissipated as it moves through the wire. This will render the excessive inductive voltage harmless. The fact that the inductive voltage will travel through the diode in the forward bias direction means the 0.7-1 volt drop across the diode junction will also limit the V=< (dv/dt) surge. Fig. 4 (below) illustrates an example of the diode connected across the coil of a solenoid that is powered with DC voltage.
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.
A diode is a semiconductor electrical component that allows an electric current in only one direction. A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).

v peak = v rms times square root (2) Note: A junction voltage of 0.3V is atypical. Normally a silicon diode has a forward voltage between 0.6 volts to 1.4V depending on current. Are you sure about the forward voltage? Perhaps you are talking about germanium or schottky diodes?

I believe hard switching is fast on/off times with inductive loads. The fast rise and fall may create voltage spikes.
The switching frequency in a drive system affects both its performance and efficiency. Higher switching frequencies can lead to improved response times and reduced output voltage ripple, enhancing overall control and performance. However, this can also increase switching losses, generate more heat, and require better thermal management. Conversely, lower switching frequencies reduce losses but may lead to slower response times and increased output ripple.
Normal house current is AC meaning it alternates on a wire first going one direction then the opposite. Standard AC is 60 hz meaning it does this 60 times per second. A diode allows current flow in one direction only. If you put a diode in an AC line, you will get pulses of current going only one direction on its backside because it refuses to conduct current in the opposite direction. Capacitive and inductive filters on the pulsing side of the diode smooth the current out so that it is no longer pulses going in one direction, it is a steady stream of electrons (DC).
No. A diode can not be used as a transistor. A diode allows electricity to flow in one direction like a one way street. A transistor works the same way as putting a stop light in the one way street. It lets electricity flow at certain times and keeps electricity from flowing at certain times. Of course a diode only works when electricity is there to flow just like a one way street only works when there are cars there to ride through it.
A Schottky diode is commonly used in battery-powered colloidal silver generators to limit current. Its low forward voltage drop allows efficient operation while preventing reverse current flow, which can protect the circuit and components. Additionally, Schottky diodes are fast-switching, making them suitable for applications where quick response times are essential. This helps ensure consistent current levels during the generation process.
Because the insulation between the gate and the channel is only a reverse biased PN junction. If this junction were to become forward biased the jfet would no longer operate as a transistor at those times.
