The breakdown voltage of the 1N4007 diode is around 1000 volts. What is the breakdown voltage of 1N4007 diode? The 1N4007 diode can handle up to 1A of current. How much current can a 1N4007 diode handle? What is the difference between 1N4001 and 1N4007 diodes?ġN4001 diodes have a peak repetitive reverse voltage of 50 volts, while 1N4007 diodes have a peak repetitive reverse voltage of 1000 volts. Diotec Semiconductor – 10D4, 1N2070, 1N3549 Ī 1N4007 diode is a silicon rectifier that is used for converting alternating current (AC) to direct current (DC).

Of course such a popular diode could not ignore the world manufacturers of semiconductors and released their full analogs: Theoretically, these diodes could be used in a 220W switching power supply, if a good heat sink from diodes is ensured (for example, by filling them with compound), but one should not go so extreme with these diodes and in the input rectifier of 220W power supply one should not exceed 50-100W, depending on the cooling system efficiency.
In addition to the reverse voltage, an essential characteristic is the forward current, for 1N4007 it reaches 1A. diode voltage drop at current 1.0 A – 1.1 V.maximum pulse current at pulse duration of 3.8 ms – 30 A.maximum long-term forward current at 167☏ (75☌) – 1.0 A.

You can put 1N4007 everywhere, even if you need to replace a diode from this series for a lower voltage during repair.ĥ Final Words Diode 1N4007 Сharacteristics
Since the cost of diodes of all series 1N4001-1N4007 is very low, and the difference in cost between the types is practically none, then there is no special point in using different types in developments and proliferate the nomenclature. 1N4007 is designed for the highest voltage. These types of diodes differ in the value of maximum permissible reverse voltage (the values for each type are given in the table). Since the 1N4007 is made with sufficient pin length, the diode can be mounted vertically or horizontally.ĭiode 1N4007 is one of the representatives of the whole series of diodes 1N4001, 1N4002, 1N4003, 1N4004, 1N4005, 1N4006, 1N4007. The colored ring on the case of the 1N4007 indicates the cathode terminal. But if your benchtop power supply has more than one watt then it is better to use a diode bridge since unipolar rectification gives much more ripple and this mode is much more difficult for the filter capacitors. A diode passes current only in one direction, cutting off one of the polarities.īy the way the cheapest chargers use half-period rectification and save three of the 4 diodes. Even if you’re holding a dollar charger and there’s no stabilization or interference filters inside, it can’t do without a diode.Īnd in one adapter, there are four diodes and a diode bridge on them, and it’s used to make an AC voltage into a DC voltage. The 1N4007 diode is probably the most popular of all diodes, since it is installed in the vast majority of chargers for phones, smartphones and tablets.
