Fast Diode
A fast diode is a faster-than-standard current rectifier. The terms "fast" and "ultrafast" are in comparison to standard rectifiers designed for low-frequency applications such as rectifying sinusoidal current supplied from the AC mains. A “fast” rectifier typically recovers ten times faster than a standard rectifier, and an “ultrafast” designation is usually applied to rectifiers designed to beat the standard rectifier recovery by being more than fifty times faster. Categorization as "ultrafast", "fast", or "soft" is in reference to the diode's reverse recovery characteristics. "Fast" and "ultrafast" rectifiers are so termed because they cease conducting current in the reverse direction much more quickly than standard rectifiers. "Soft" is a term applied to a subset of ultrafast rectifiers that recover to the non-conducting state quickly, but in a non-abrupt manner.

Rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an inverter. The process is known as ''rectification'', since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium oxide plates, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a " cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detector". Rectifiers have many uses, but are often found serving as components of DC power supplies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-mount Device
Surface-mount technology (SMT), originally called planar mounting, is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality. It also allows for more components to fit on a given area of substrate. Both technologies can be used on the same board, with the through-hole technology often used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors. An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DO-41
DO-204 is a family of diode semiconductor packages defined by JEDEC. This family comprises lead-mounted axial devices with round leads. Generally a diode will have a line painted near the cathode end. Dimensions Common variants Several common packages are archived in DO-204 as variants, and may be referred to using their alternative names. DO-7 The DO-7 (also known as DO-204-AA) is a common semiconductor package for 1N34A germanium diodes. DO-35 The DO-35 (also known as DO-204-AH or SOD27) is a semiconductor package used to encapsulate signal diodes (i.e., diodes meant to handle small amounts of current and voltage). It is often used to package small signal, low power diodes such as 1N4148 (a 100 V, 300 mA silicon diode.)

Diode
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 diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used. Among many uses, diodes are ...

Woodbine Municipal Airport is a public use airport located two nautical miles (4 km) southeast of the central business district of Woodbine, in Cape May County, New Jersey, United States. The airport is owned by the Woodbine Port Authority. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''general aviation'' facility. Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned OBI by the FAA, but has no designation from the IATA (which assigned OBI to an airport in Óbidos, Pará, Brazil).
