Diode - Wikipedia
网页A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other.
A Complete Guide to Diodes - Circuit Basics
网页2021年10月25日 · A diode is a specialized electronic component that acts as a one-way switch. It conducts electric current in only one direction and restricts current from the opposite direction. A diode is reverse biased when it acts as an insulator and is forward biased when it allows current to flow. A diode has …
Diodes - SparkFun Learn
网页The positive end of a diode is called the anode, and the negative end is called the cathode. Current can flow from the anode end to the cathode, but not the other direction. If you forget which way current flows through a diode, try to remember the mnemonic ACID: "anode current in diode" (also anode cathode is diode).
Diodes Explained - The Engineering Mindset
网页2020年1月19日 · A diode looks something like the image above and comes in different sizes. They typically have a black cylindrical body that has a stripe at one end as well as some leads coming out to allow us to connect it into a circuit. This end is known as the anode and this end is the cathode and we’ll see what that means later in the video.
Diode | Definition, Symbol, Types, & Uses | Britannica
网页2024年9月26日 · Diode, an electrical component that allows the flow of current in only one direction. The most common type of diode uses a p-n junction in which one material (n) has electrons as charge carriers next to a second material (p) with holes (places depleted of electrons) as charge carriers.
Introduction to Diodes And Rectifiers | Diodes and Rectifiers ...
网页A diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other. The most common kind of diode in modern circuit design is the semiconductor diode, although other diode technologies exist. Semiconductor diodes are symbolized in schematic diagrams such as the figure below.
Diode: Definition, Symbol, and Types of Diodes | Electrical4U
网页2024年4月20日 · A diode is defined as a two-terminal electronic component that only conducts current in one direction (so long as it is operated within a specified voltage level). An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction.
网页A diode is constructed by fabricating p and n regions in Si as shown schematically on Figure 3(a). The symbol of the diode and the corresponding arrangement of the p and n regions is shown on Figure 3(b). The boundary between the p and the n regions is called the p-n junction. p region n region + Vd - Id (a) Id + Vd - (b) Figure 3
How Diodes Work: Understanding the Fundamentals
网页2020年1月29日 · Learn about diodes, a fundamental electronic component that allows current to flow only in one direction. With this video tutorial, explore every aspect of diodes, from their detailed characteristics to their functions and some important terms.
