Diodes are a key component in any electronic device and are integrated into a variety of circuits. One of the most basic and essential types of diodes is the single, rectifier diode. The PDU620-13 is a single rectifier diode that is used extensively in a wide range of applications. In this article we will look at what it is, what it does and how it functions.

The PDU620-13 is a single rectifier diode designed for high voltage applications. It is a PN-type diode, meaning it is composed of two distinct parts, one anode, the other a cathode. The anode is a semi-insulating n-type of material, whilst the cathode is made up of a p-type material. The two types of material allow charge to flow between them in only one direction.

The PDU620-13 can handle voltage up to 800V, and the maximum current is 1.3A. Current flow starts at a ‘back bias’ voltage of one volt, and breaking over-voltage is normally set between 700V-1000V. The PDU620-13 also has a relatively low forward voltage drop, which can help to keep the voltage in a circuit stable.

The PDU620-13 has a wide range of applications, including in power supplies, motor controller circuits, lighting systems, solar cell circuits, and automotive applications. In these applications, the diode can help to limit current flow to within a predetermined safe range, preventing damage to sensitive equipment from an overload of current. It can also be used as a surge protection diode, power dissipation or as part of protection relays.

As far as its working principle goes, the PDU620-13 works by controlling the voltage flow in two fundamental ways. The first way is by creating a high forward bias voltage, which forces the electrode current flow in the anode to flow only in one direction. Once the forward bias voltage becomes large enough, the movement of electrons across the barrier between the anode and cathode is stopped.

The second way the PDU620-13 operates is by creating a reversed bias voltage, that offers negative voltage that opposes the flow of current from the anode to the cathode. When this voltage is large enough, a zone of ‘depletion’ develops, causing an electric field that stops electron current flow.The PDU620-13 is an essential component in many electronic circuits and systems. Its ability to control the flow of current in both directions helps to ensure that sensitive components are not overloaded or damaged by overcurrents, as well as helping to maintain a stable voltage throughout the circuit.
