For positive voltages there is high impedance up to the reverse bias breakdown voltage.

What is a unidirectional diode. And when the positive terminal of battery connected to the p side and other terminal connected to the other terminal of diode then diode is called forward biased. A diode is a semiconductor device that essentially acts as a one way switch for current. Please respond quickly as i do not have too much hair left to pull.

A diode is unidirectional because of the diode only conduct in forwardbias as you know the diode have two terminal cathode and anode. A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode but is made and tested to handle very large peak currents. Call me an olde geezer but i seem to remember that a diode is supposed to be uni directional.

A diode is unidirectional because of the diode only conduct in forwardbias as you know the diode have two terminal cathode and anode. A unidirectional transient voltage suppressor diode works as a rectifier in a circuit in the forward direction like any other avalanche diode and this unidirectional diode is made to withstand very large peak currents. Data diodes can be found most commonly in high security environments such as defense where they serve as connections between two or more networks of differing security classifications.

A unidirectional network also referred to as a unidirectional gateway or data diode is a network appliance or device that allows data to travel in only one direction. A bidirectional transient voltage suppression diode can be represented by two mutually opposing avalanche diodes in series with one another and connected in parallel with the circuit to be protected. And what is it used for.

And when the positive terminal of battery connected to the p side and other terminal connected to the other terminal of diode then diode is called forward biased. For negative voltage from cathode to anode the tvs has high conductivity above a forward diode drop. It allows current to flow easily in one direction but severely restricts current from flowing in the opposite direction.

Symbol of a unidirectional tvs diode is shown in below image and it is much like a zener diode. Above the reverse bias breakdown voltage the diode has low resistance.
