Reverse Bias

Some articles on reverse bias, reverse, bias:

Gate Turn-off Thyristor - Reverse Bias
... GTO thyristors are available with or without reverse blocking capability ... Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low doped P1 region ... GTO thyristors capable of blocking reverse voltage are known as Symmetrical GTO thyristors, abbreviated S-GTO ...
Semiconductor Diodes - Shockley Diode Equation
... Shockley) gives the I–V characteristic of an ideal diode in either forward or reverse bias (or no bias) ... The equation is where I is the diode current, IS is the reverse bias saturation current (or scale current), VD is the voltage across the diode, VT is the thermal voltage, and n is the ... The reverse saturation current, IS, is not constant for a given device, but varies with temperature usually more significantly than VT, so that VD typically ...
Semiconductor Diodes - Current–voltage Characteristic
... This is the reverse bias phenomenon ... with respect to the N-doped region and the diode is said to be "turned on" as it has a forward bias ... At very large reverse bias, beyond the peak inverse voltage or PIV, a process called reverse breakdown occurs that causes a large increase in current (i.e ...
MOSFET Operation - Body Effect
... Application of a source-to-substrate reverse bias of the source-body pn-junction introduces a split between the Fermi levels for electrons and holes, moving the Fermi level for the channel ... This change in channel strength by application of reverse bias is called the body effect ... using an nMOS example, the gate-to-body bias VGB positions the conduction-band energy levels, while the source-to-body bias VSB positions the electron Fermi level near ...
List Of LED Failure Modes - Stress-related
... Reverse bias Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any. 5V is a typical, "maximum reverse bias voltage" figure for ordinary LEDs some special types may have lower limits ...

Famous quotes containing the words bias and/or reverse:

    The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.
    Ralph Waldo Emerson (1803–1882)

    Now listen, buddy, there are a few corny ideas you got to get out of your head if you’re going to fly an airplane. Most things are just the reverse from what people think. The higher you are the safer you are. The Earth down there, that, that’s your enemy because once you hit that, boy, you splatter.
    Dalton Trumbo (1905–1976)
