The limitation on forward bias in a semiconductor, such as a diode, primarily relates to the maximum current that can flow through the device without causing damage or overheating. Beyond a certain threshold, known as the forward current rating, the diode may experience thermal runaway, leading to failure. Additionally, high forward bias can result in increased leakage current and reduced efficiency in electronic circuits. Proper thermal management and circuit design are essential to mitigate these limitations.
forward bias
forward bias is in the direction a junction or vacuum tube wants to conduct currentreverse bias is in the direction a junction or vacuum tube opposes conducting current
characteristics of forward biased
A silicon transistor needs about 0.65 v of forward bias on the base to begin to conduct.
The ammeter is connected in different way in forward and reverse bias zenner diode. So that all of the board will work right going forward and reverse.
The limitation on forward bias in semiconductor devices, such as diodes, is primarily related to the maximum current that can flow through the device without causing thermal breakdown or damage. Excessive forward bias can lead to increased carrier injection, resulting in overheating and potential failure. Additionally, the forward voltage drop becomes significant at higher currents, affecting efficiency and performance. Finally, in practical applications, there are also considerations like power dissipation and circuit design that impose constraints on the level of forward bias used.
Forward bias implies that your device is sensitive to bias direction and you have selected one of them. There is also an implication that it is probably a steady bias. So forward bias generally implies a dc bias in a selected direction called forward bias in the device you are looking at. Now the question is actually put the other way round. DC bias means a steady state bias. Whether or not it is forward or reverse bias depends on whether or not the device is sensitive to the direction of bias. If it is not sensitive to that, it isn't forward bias (or reverse bias either). If it is sensitive to bias direction, then it would be in a state of either forward bias or reverse bias, and you would need more information in order to say which one. So, finally, the phrase "dc biased" is NOT the same thing as "forward biased".
