1N58xx Schottky Diodes
The 1N58xx is a series of medium power, fast, low voltage Schottky diodes, which consists of part number numbers 1N5817 through 1N5825. Overview The 1N581''x'' are typically packaged in the DO-41 axial through-hole case, and in many cases are interchangeable with the 1N4001 series. The 1N582''x'' are typically packaged in the DO-201AD through-hole case, and in many cases are interchangeable with the 1N54''xx'' series. Being Schottky diodes, the 1N58''xx'' parts have roughly half the forward voltage drop of the 1N400''x''/1N540''x'' series diodes, which improves efficiency in applications where they are usually forward-biased, such as power converters. The cost is a lower voltage rating and higher reverse leakage current (approximately 1 mA at room temperature and increasing with temperature). Common surface-mount relatives of the 1N58xx series are the SS1x and SS3x series, such as the SS14 (1 ampere) and SS34 (3 ampere) surface-mount parts. See also * 1N400x general-pu ...

Surface-mount Technology
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 lead (electronics), pins or leads of various styles, flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TSMC
Taiwan Semiconductor Manufacturing Company Limited (TSMC; also called Taiwan Semiconductor) is a Taiwanese multinational semiconductor contract manufacturing and design company. It is the world's most valuable semiconductor company, the world's largest dedicated independent ( pure-play) semiconductor foundry, and one of Taiwan's largest companies, with its headquarters and main operations located in the Hsinchu Science Park in Hsinchu. It is majority owned by foreign investors. Founded in Taiwan in 1987 by Morris Chang, TSMC was the world's first dedicated semiconductor foundry and has long been the leading company in its field. When Chang retired in 2018, after 31 years of TSMC leadership, Mark Liu became chairman and C. C. Wei became Chief Executive. It has been listed on the Taiwan Stock Exchange (TWSE: 2330) since 1993; in 1997 it became the first Taiwanese company to be listed on the New York Stock Exchange (NYSE: TSM). Since 1994, TSMC has had a compound annual growth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsemi
Microsemi Corporation was an Aliso Viejo, California-based provider of semiconductor and system solutions for aerospace & defense, communications, data center and industrial markets. In February 2018, it was announced that Chandler, Arizona-based Microchip Technology was acquiring the company for over US$10 billion, pending regulatory approval. In May 2018, it was announced that Microchip had completed its acquisition of Microsemi. In August 2018, Microchip discovered that Microsemi shipped large orders to distributors on discount before the closing of the acquisition and had a culture of excessive extravagance, casting some doubt on the future prospect of the acquisition. History 1959 to 1970: Early years Microsemi was founded in February 1959 in Culver City, California as MicroSemiconductor. It incorporated in Delaware on September 27, 1960. A trade catalog and price lists from this early period can be found at the Smithsonian Institution. In March 1963, A. Feldon repre ...

1N4148 Signal Diode
The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns. History Texas Instruments announced the 1N914 diode in 1960. It was registered at JEDEC by Texas Instruments no later than 1961, and was second-sourced by 11 manufacturers that same year. The 1N4148 was registered at JEDEC in 1968 as a silicon switching signal diode for military and industrial applications. It was second-sourced by many manufacturers; Texas Instruments listed their version of the device in an October 1966 data sheet. These 1N914 and 1N4148 have an enduring popularity in low-current applications. Overview As the most common mass-produced switching diode, the 1N4148 replaced the older 1N914, they can be used interchange ...

1N400x General-purpose Diodes
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). Facilities and aircraft Woodbine Municipal Airport covers an area of 700 acres (283 ha) at an elevation of 42 feet (13 m) above mean sea level. It has two runways with asphalt surfaces: 1/19 is 3,304 by 75 feet (1,007 x 23 m) and 13/31 is 3,073 by 75 feet (937 x 23 m). For the 12-month period ending January 1, 2011, the airport had 12,375 general aviation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reverse Leakage Current
Reverse leakage current in a semiconductor device is the current from that semiconductor device when the device is reverse biased. When a semiconductor device is reverse biased it should not conduct any current, however, due to an increased barrier potential, the free electrons on the p side are dragged to the battery's positive terminal, while holes on the n side are dragged to the battery's negative terminal. This produces a current of minority charge carriers and hence its magnitude is extremely small. For constant temperatures, the reverse current is almost constant although the applied reverse voltage is increased up to a certain limit. Hence, it is also called reverse saturation current. The term is particularly applicable to mostly semiconductor junctions, especially diodes and thyristors A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage Drop
Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated. The voltage drop across the electrical load is proportional to the power available to be converted in that load to some other useful form of energy. For example, an electric space heater may have a resistance of ten ohms, and the wires that supply it may have a resistance of 0.2 ohms, about 2% of the total circuit resistance. This means that approximately 2% of the supplied voltage is lost in the wire itself. An excessive voltage drop may result in the unsatisfactory performance of a space heater and overheating of the wires and connections. National and local electrical codes may set guidelines for the maximum voltage drop allowed in electrical wiring to ensure efficiency of distri ...
