TO-66
TO-66 is a type of semiconductor package for devices with three connections, such as transistors. The shape is similar to the TO-3 package, but the size is smaller. The TO-66 package is made entirely of metal and is commonly used by silicon controlled rectifiers and power transistors. In Europe, it was popularly used by the complementary germanium power transistors AD161/AD162. The TO-66 package consists of a diamond-shaped base plate with diagonals of and . The plate has two mounting holes on the long diagonal, with the centers spaced apart. A cap attached to one side of the plate and under which the semiconductor chip is located, brings the total height to up to . Two pins on the other side of the plate are isolated from the package by individual glass-metal seals. The metal case forms the third connection (in the case of a bipolar junction transistor this is typically the collector). Variants TO-66 is often used as a synonym for any of the variants that have the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TO-126
TO-126 is a type of semiconductor package for devices with three pins, such as transistors. The package is rectangular with a hole in the middle to allow for easy mounting to a board or a heat sink. On one side of the package typically a metal sheet is exposed, with the transistor die bonded to the other side of the metal sheet inside the package. This allows for an efficient heat transfer from the transistor die to an external heat sink but also implies that the metal sheet is electrically connected to the die (for a bipolar junction transistor usually the collector is connected to this metal sheet). History and origin The JEDEC TO-126 descriptor is derived from the original full name for the package: Transistor Outline Package, Case Style 126. In the updated JEDEC outline system, the package is numbered as TO-225AA. STMicroelectronics refers to this package style as SOT-32.

Pro Electron
Pro Electron or EECA is the European type designation and registration system for active components (such as semiconductors, liquid crystal displays, sensor devices, electronic tubes and cathode ray tubes). Pro Electron was set up in 1966 in Brussels, Belgium. In 1983 it was merged with the European Electronic Component Manufacturers Association (EECA) and since then operates as an agency of the EECA. The goal of Pro Electron is to allow unambiguous identification of electronic parts, even when made by several different manufacturers. To this end, manufacturers register new devices with the agency and receive new type designators for them. Designation system Examples of Pro Electron type designators are: * AD162 – Germanium power transistor for audio frequency use * BY133 – Silicon rectifier * BZY88C5V1 – Silicon 5.1 volt Zener diode * CQY97 – light emitting diode * ECC83 – 6.3 volt heater noval dual triode * A63EAA00XX01 – Color T ...

TO-3
In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits. ''TO'' stands for "Transistor Outline" and relates to a series of technical drawings produced by JEDEC. The TO-3 case has a flat surface which can be attached to a heatsink, normally via a thermally conductive but electrically insulating washer. The design originated at Motorola around 1955 from a group headed by Dr. Virgil E. Bottom. who was director of research of the Motorola Semiconductor Division. The first use of this design was for the germanium alloy-junction power transistor 2N176 – the first power transistor to be put into quantity production. The lead spacing was originally intended to allow plugging the device into a then-common tube socket. Typical applications The metal package can be attached to a heat sink, making it suitable for devices dissipating several watts o ...

Kombinat Mikroelektronik Erfurt
VEB Kombinat Mikroelektronik Erfurt was an important manufacturer of active electronic components in East Germany. It should not be confused with the more well-known VEB Kombinat Robotron Dresden which used integrated circuits from Kombinat Mikroelektronik in its computers. Their products often carried the trademark RFT, but this was used on most electronic products from East Germany from otherwise unrelated companies. History The Kombinat Mikroelektronik Erfurt was formed in 1978 when the ''VVB Bauelemente und Vakuumtechnik'' was split into ''VEB Kombinat Elektronische Bauelemente Teltow'' for passive electronic components and ''VEB Kombinat Mikroelektronik Erfurt'' for active electronic components. However, the history of many of the individual plants reaches back further, in some cases to before the Second World War. In 1971 the first integrated circuits had been manufactured — the D100C ( TTL) by Halbleiterwerk Frankfurt (Oder) and the U101D ( PMOS logic) by Funkwerk ...

Rosstandart
Federal Technical Regulation and Metrology Agency (Rosstandart) (russian: Федеральное агентство по техническому регулированию и метрологии (Росстандарт)) is the Russian federal government agency that serves as a national standardization body of the Russian Federation. It was previously known as Gosstandart. It is subordinated to the Ministry of Industry and Trade. History On September 15, 1925, by a resolution of the Council of People's Commissars of the USSR, an all-Union body in the field of standardization was created, the Committee for Standardization under the Council of Labor and Defense (Gosstandart). The introduction of state management of standardization in the country served as the beginning of systematic work in all sectors of the economy. On May 7, 1926, the first all-Union standard was approved - OST 1 “Wheat. Breeding grades of grain. Nomenclature". In 1946, the International Organization for ...

GOST
GOST (russian: ГОСТ) refers to a set of international technical standards maintained by the ''Euro-Asian Council for Standardization, Metrology and Certification (EASC)'', a regional standards organization operating under the auspices of the Commonwealth of Independent States (CIS). All sorts of regulated standards are included, with examples ranging from charting rules for design documentation to recipes and nutritional facts of Soviet-era brand names. The latter have become generic, but may only be sold under the label if the technical standard is followed, or renamed if they are reformulated. The notion of GOST has certain significance and recognition in the countries of the standards' jurisdiction. The Russian government Federal Agency on Technical Regulating and Metrology (Rosstandart) has ''gost.ru'' as its website address. History GOST standards were originally developed by the government of the Soviet Union as part of its national standardization strategy. The ...

Gosstandart
Gosstandart (russian: Госстандарт) was the Soviet government agency responsible for standardization, metrology, and quality management. The name is an abbreviation for ''Gosudarstvennyy standart'' (‘State Standard’). History Established in 1925 as a committee for standardization within the USSR Council of Labor and Defence, ''Gosstandart'' was at first put in charge of inspecting measuring instruments used in industrial and agricultural production and later was tasked with developing, updating, and disseminating GOST standards. Over the course of its existence, the agency was reformed a number of times, receiving a new name with each transformation: the ''National Committee for Standardization''; the ''Committee for Standards, Metrology, and Measuring Instruments''; the ''State Committee for Standards''; the ''State Committee for Standards and Product Quality Management''. The agency received its nickname, ''Gosstandart'', in 1970. Later years After the dissoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Standards
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to: Formally, as stated in a 2002 memorandum of understanding between the BSI and the United Kingdom Government, British Standards are defined as: Products and services which BSI certifies as having met the requirements of specific standards within designated schemes are awarded the Kitemark. History BSI Group began in 1901 as the ''Engineering Standards Committee'', led by James Mansergh, to standardize the number and type of steel sections, in order to make British manufacturers more efficient and competitive.
