Diode Definition: A diode is defined as a component that restricts the direction of flow of electric current, mainly allowing current to pass in one direction. Symbol and Orientation: The diode symbol represents the direction of conventional current flow, from the anode to the cathode. ...
Though small and simple, the diode is an essential part of modern electrical systems. By controlling the flow and direction of current, diodes enable countless applications of modern electronics. Fortunately, tools like digital multimeters make it easy to measure diode health and determine when it’...
At least one junction diode fabricated in standard CMOS logic processes can be used as program selectors for memory cells that can be programmed based on direction of current flow. These cells are MRAM, RRAM, CBRAM, or other memory cells that have a programmable resistive element coupled to a...
The heated cathode generates a cloud of electrons that are attracted by the anode, causing a current to flow from the cathode to the anode. Because the anode cannot generate electrons of its own, the current cannot flow in the opposite direction. ...
direction of current flow, i.e., positive (+) to negative (-). Hence, a diode permits the flow of current in the direction of the arrow. And then consider the vertical line on the cathode side as an enormous minus sign (-), depicting which side of a diode is negative for forward-...
The reverse saturation current is the order ofmicro-ampere (μA). How reverse current is produced in a diode? If a large enough negative voltage is applied to the diode, it will give in and allow current to flow in the reverse direction. This large negative voltage is called the breakdown...

This semi-conductor device permits the flow of current in a unidirectional way. Provided with sufficient voltage, they allow the flow of current in the opposite direction as well. The excess voltage required for reversing the direction of flow of current is termed as breakdown voltage or Zener ...
Diode The term 'Diode' as it applies to the area of photovoltaics can be defined as ' Electronic component that allows current flow in one direction only. See Blocking Diode & Bypass Diode'. About the author Mark McCracken Author: Mark McCracken is a corporate trainer and author living in ...
