diode current flows only when the diode is forward biased because in reverse bias the barrier potential increases. Diode can conduct in reverse bias if applied votage is high enough to overcome the reverse bias barrier potential but it can be destructive.
when a diode is forward biased it conducts current
If it's a silicon zener diode, it conducts in the reverse direction after the rated voltage is reached. Otherwise, it only conducts in the forward bias direction.
we can conclude that the standard diode conducts current when connected in forward bias mode.
It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.
A A diode has two state either on [forward conduction .7 volts. Or reversed bias meaning the diode voltage polarity are revered or cut off, depends on the diode but it will leak some current , Anyhow that is reversed bias diode conditionForward conduction voltage can vary between about 0.6 volts and about 1.4 volts depending on the diode and the current. Also, some diodes, such as zener diodes, will conduct in the reverse direction. Reverse bias is simply where the anode is more negative than the cathode.
Forward biased is the configuratiuon that a diode conducts.
when a diode is forward biased it conducts current
diode it conducts when it is forward bised in reverse bias there is breakdown
A diode is a semiconductor material which has p region and n region. In order to "turn on" and conduct current in the forward direction, a diode requires a certain amount of positive voltage to be applied across it. An ideal diode conducts only when the diode is forward biased, and then the voltage drop across the diode (Vd) is zero. When the ideal diode is reverse biased, no current flows. The two conditions to operate a diode are: (a) Current flow is permitted; the diode is forward biased. (b) Current flow is prohibited; the diode is reversed biased. 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.
If it's a silicon zener diode, it conducts in the reverse direction after the rated voltage is reached. Otherwise, it only conducts in the forward bias direction.
because in forward connection the internal field is in a direction of the main current so the current passes while in the backward connection it is reversed so no current passes
we can conclude that the standard diode conducts current when connected in forward bias mode.

A forward bias A positive pulse to the gate of the thyristor.
The diode conducts at its forward breakdown voltage. Depending on the current, and the type of diode, the voltage could be anywhere between 0.2 and 3.5 volts, with a nominal silicon range of 0.7 to 1.4.
The key function of a diode is to control the direction of the flow of current. Current passing through a diode can only go one way, which is called forward biased. In this setup, current is continuous hence the circuit is closed. When there is no current passing through, there will be no flow, and this is called reversed biased. In such a case, current is not continuous, hence it is called open circuit.
