☑ Reverse Bias Diode Current Flow

Forward bias means connecting anode to p type and cathode to n type. When the polarity of the battery is such that current is allowed to flow through the diode the diode is said to be forward biased.

Forward bias allows current to flow through the diode.

Reverse bias diode current flow. In reverse biased p n junction diode the positive terminal of the battery is connected to the n type semiconductor material and the negative terminal of the battery is connected to the p type semiconductor material. In a zener diode this is designed to be the normal operating mode of the diode. A pn junction diode allows electric charges to flow in one direction but not in the opposite direction.

In this mode current flow is mostly blocked and the diode is off. This reverse saturation is because of thermal movement of electrons and holes that is why reverse saturation current only depends upon the temperature not on the applied voltage. In an ordinary diode this can destroy the diode unless current limiting is provided.

For no external voltage there is no net current flowing in the diode. Reverse bias means connecting anode to n type and cathode to p type. Voltage connected to the diode in this direction is called reverse bias.

The diode acts like a closed switch in forward bias. Up to a point anyway. A very small amount of current on the order of na called reverse saturation current is able to flow in reverse through the diode.

B current flow is prohibited. Reverse bias doesnt allow current to flow. This is the off mode of the diode where the voltage is less than v f but greater than v br.

Conversely when the battery is backward and the diode blocks current the diode is said to be reverse biased. Negative charges electrons can easily flow through the junction from n to p but not from p to. The forward bias reduces the potential barrier of the diode and establishes the easy path for the flow of current.

The forward bias and the reverse bias properties of the pn junction imply that it can be used as a diode. Voltage connected to the diode in this direction is called forward bias. The diode is reversed biased.

The diode acts like an open switch in reverse bias. Reverse saturation current flows when you reverse bias a diode. Bias is the application of a voltage across a pn junction.

In effect the diode becomes an insulator. The process by which a p n junction diode blocks the electric current in the presence of applied voltage is called reverse biased p n junction diode. Biasing means the electrical supply or potential difference is connected to the semiconductor device.

The potential difference is of two types namely forward bias and the reverse bias. But if you reverse the voltage direction applying the positive side to the cathode and the negative side to the anode current doesnt flow. Forward bias is in the direction of easy current flow and reverse bias is in the direction of little or no current flow.

If the reverse voltage exceeds the reverse breakdown voltage current flows in a diode in reverse bias.
