Diode 1N4007 - an ideal tool for building powerful rectifying bridges
The diode 1N4007 is a powerful semiconductorThe device that is most often used in power supplies. To be more precise - in their rectifying part, that is, in the diode bridge. Its main task is to convert the alternating voltage into a constant voltage, on which most microelectronic components work today. The principle of the diode is as follows. In one direction it is open, and a signal passes through it without problems. If you change the polarity of the signal, it closes and practically does not pass anything through itself.
Characteristics
The main characteristics of the diode 1N4007 is as follows:
- weight 0.35 g;
- the maximum temperature at soldering 250 degrees on a scale of Celsius no more than 10 seconds;
- the cathode is designated by a special ring, which is applied to the body;
- maximum (it is also called "peak") voltage - not more than 1000 V;
- the operating temperature range is from -55 to +125 degrees Celsius;
- The maximum value of the current through the device should not exceed 1 A;
- the maximum voltage drop with an open p-n junction is not more than 1 V at a current value of 1 A.
If we pay attention to the largest permissiblethe value of the potential, it can be understood that this is a powerful diode that will work quietly with 220 or 380 V. Based on this, it can be said that it was originally designed for power supplies. The diode 1N4007 is most often found in the rectifying part of the circuit.
Appointment
The main applications of 1N4007 are diodebridges. Another, less common field of their use is power electronics. It can be various analog amplifiers. In this case, their implementation can significantly improve the characteristics of the final device. Also, they can be used in regulated power sources, where he managed to prove himself well.
Family
1N4007 is only one of the representatives of the wholefamily of this class of devices. This also includes 1N4001-1N4006. That is, the last index changes in this series. The smaller it is, the less powerful a semiconductor element is used. With great confidence we can say that 1N4007 is the most universal and can replace any representative of this family, since it is the most powerful one.
Analogues
A complete analogue of the diode 1N4007 among domestic semiconductor products is the KD258D. In turn, similar characteristics are possessed by:
- 10D4, 1N2070, 1N3549 - products of Diotec Semiconductor company;
- BY156, BYW27-1000 - from Thomson;
- BYW43 - from Philips;
- HEPR0056RT is from Motorola.
On this possible list of analogs does not end, but this is the most common replacement options.
Conclusion
Widely used for various modificationspower supplies semiconductor element 1N4007. A diode of this class is simply indispensable when creating or repairing most devices of this type. He can replace any unit of his family without problems. 1N4007 features high reliability, low cost, as well as versatility. It is due to these factors, he found wide application.
