1N4007 diode is an electronic diode under the family of 1N400× series. It is a very popular diode due to the variety of functions it performs, low cost, and compatible size of it. 1N400× family series diode has a range of diodes, from 1N4001 – 1N4007. They have similar functions and pinouts in a circuit with similar pin configurations but differ in power ratings.
This type of diode is used for the rectification of AC signals. That is to convert an AC signal to a DC signal. It can also be used for other general purposes like inverting signals. In this post, we will go into detail to discuss its power specifications and its data sheets.

What is the 1N400X family series diode?
1N400X series diodes were first introduced by Motorola semiconductor products divisions on the year 1963.
The 1N400X series diodes belong to 1-ampere silicon rectifying diode which has different diodes from 1N4001 – 1N4007. With different reverse voltages in each range. Their blocking voltage is from 50V for the 1N4001 and 1000V for 1N4007. They are mostly used for AC adapters our electronic devices.
The table below shows the 1N400X series with their blocking reversed voltage.

1N4007 replacement and equivalent.
There are some sets of diodes that we can use in place of the 1N4007 diode. But where to focus more should be on the level of power we are working with. Not all diodes can be able to withstand a certain voltage you might be working with. You can make use of the 1N4001 – 1N4007 diode in place of another one only when the voltage range you are working with falls between their voltage range.
When the voltage range you are working with is greater than 800V but below 1000V, use HER158, HER208, FR207, and FR107 diodes as they can serve as equivalents for 1N4007. But in case you are working with a voltage range above 1000V then you should go for EM513, EM520, or 1N5399 diode as a replacement.
Another equivalent diode of 1N4007 are;
- 1N4007-T
- 1N5408
- STTH110
- BA159
