The 1N4007 diode is a powerful semiconductor device that is most often used in power supplies. To be more precise - in the rectifying part, that is, in the diode bridge. Its main task is to convert alternating voltage into direct voltage, on which most microelectronic components operate today. The principle of operation 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 will close and practically will not let anything through itself.
The 1N4007 diode is produced in Taiwan. At the same time, the
production capacities of DIODES and RECTRON SEMICONDACTOR are involved. There are products of other brands, but much less often.
Characteristics
The main characteristics of the diode 1N4007 has the following:
- weight 0.35 g;
- maximum temperature when soldering 250 degrees Celsius not more than 10 seconds;
- the cathode is indicated by a special ring that is applied to the housing;
- maximum (it is also called "peak") voltage - no more than 1000 V;
- operating temperature range is from -55 to +125 degrees Celsius;
- the highest value of the current through the device should not exceed 1 A;
- the maximum voltage drop with an open pn junction is not more than 1 V at a current value of 1 A.
If you pay attention to the maximum permissible value of the potential, you can understand that this is a powerful diode that will work quietly with 220 or 380 V. Based on this, we can say that it was developed initially for power supplies. Diode 1N4007 is most often found precisely in the rectifier part of the circuit.
Appointment
The main scope of 1N4007 is diode bridges. Another, less common area of their use is power electronics. It can be various analog amplifiers. In this case, their implementation can significantly improve the characteristics of the end device. You can also use them in regulated power supplies, where he managed to prove himself perfectly.
Family
1N4007 is only one of the representatives of a whole family of this class of devices. This also includes 1N4001-1N4006. That is, in this series, the last index changes. The smaller it is, the less powerful a semiconductor element is used. With great certainty, we can say that 1N4007 is the most universal and can replace any member of this family, since it is the most powerful.
Analogs
A complete analogue of the diode 1N4007 among domestic semiconductor products is KD258D. In turn, similar characteristics have:
- 10D4, 1N2070, 1N3549 - products of Diotec Semiconductor;
- BY156, BYW27-1000 - from Thomson;
- BYW43 - from Philips;
- HEPR0056RT - from Motorola.
This does not end with a possible list of analogues, but these are the most common replacement options.
Conclusion
Widely used for various modifications of power supplies, the 1N4007 semiconductor element. A diode of this class is simply indispensable when creating or repairing most devices of this type. He can easily replace any unit in his family. 1N4007 differs in high reliability, low cost, and also universality. It was due to these factors that he found wide application.
