1N4003
The 1N400x (or 1N4001 or 1N4000) series is a family of popular one-ampere general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Its blocking voltage varies from 50 volts (1N4001) to 1000 volts (1N4007). This JEDEC device number series is available in the DO-41 axial package. Diodes with similar ratings are available in SMA and MELF surface mount packages (in other part number series). The 1N540x (or 1N5400) series is a similarly popular family of diodes rated 3 Amperes. These diodes use the larger DO-201AD axial package to dissipate heat better. History The 1N400x series was originally introduced by Motorola's Semiconductor Products Division and registered at JEDEC in 1963 as silicon power rectifiers used primarily for military and industrial applications. It appeared in the Motorola ''Semiconductor Data Manual'' in 1965, as replacements for 1N2609 through 1N2617. The 1N540x series were announced in ''Electrical Design ...

Diode 1n4001
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 found in rectif ...

Flyback Diode
A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters. This diode is known by many other names, such as snubber diode, commutating diode, freewheeling diode, suppressor diode, clamp diode, or catch diode. Operation Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is applied to the inductor, causing current from the battery's positive terminal to flow down through the inductor and resistor. The increase in current causes a back EMF (voltage) across the inductor due to Faraday's law of induction which opposes the change in current. Since ...

Diode Bridge
A diode bridge is a bridge rectifier circuit of four diodes that is used in the process of converting alternating current (AC) from the input terminals to direct current (DC, i.e. fixed polarity) on the output terminals. Its function is to convert the negative-going AC pulses into positive going pulses, after which a low-pass filter can be used to smooth the result into DC. When used in its most common application, for conversion of an alternating-current (AC) input into a direct-current (DC) output, it is known as a bridge rectifier. A bridge rectifier provides full-wave rectification from a two-wire AC input, resulting in lower cost and weight as compared to a rectifier with a three-wire input from a transformer with a center-tapped secondary winding. The essential feature of a diode bridge is that the polarity of the output is the same regardless of the polarity at the input. The diode bridge circuit was invented by Polish electrotechnician Karol Pollak and patented ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

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 ...

MELF
Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device that is metallized at its ends. MELF devices are usually diodes and resistors. The EN 140401-803 and JEDEC DO-213 standards describe multiple MELF components. Handling difficulties Because of their cylindrical shape and small size, in some cases these components can easily roll off the workbench or circuit board before they have been soldered into place. As such, there is a joke which suggests an alternate meaning for the acronym: ''Most End up Lying on the Floor''. Additionally, MELF components are sometimes called a "roll away" package. During automated SMT pick-and-place, this happens mostly if the mechanical pressure of the SMD placer nozzle is too low. If the MELF components are placed into the solder paste with enough pressure, then this problem can be minimized. Care must be taken with glass diodes which are less mechanically robust than resistors and other ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
