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.
Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting.
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). [ 10 ] [ 13 ] [ 2 ] It is often used to package small signal, low power diodes such as 1N4148 (a 100 V, 300 mA silicon diode.)
A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies , sometimes as high as 90–95%, while being electrically simple circuits.
In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region, or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or been forced away by an electric field. The only elements left ...
Instead of spiking to -300 V, the flyback diode only allows approximately -1.4 V of potential to be built up (-1.4 V is a combination of the forward bias of the 1N4007 diode (1.1 V) and the foot of wiring separating the diode and the solenoid [dubious – discuss]). The waveform in Figure 2 is also smoother than the waveform in Figure 1 ...
A whole floor of a building in New York City was once functioning as an "illegal police station" for the government of the People’s Republic of China, according to the U.S. Department of Justice ...
The 1N4148 and 1N914 are not the same. The reverse current of the 1N4148 is much lower that is why it replaced the 1N914. The 1N914 is speced at 5 microamps reverse current, the 1N4148 25 nanoamps. Other than that, they are basically identical. The reverse recovery time of both is 4 nanosecond, not very fast these days.
