Last updated on April 1st, 2023 at 04:00 pm

1N4007 is a PN junction silicon rectifier diode that belongs to the 1N400x series family. Due to its small size and low cost, it is an ideal diode for a wide range of applications.

For example: in electrical circuits where rectifications of the electrical signal are needed, in voltage regulators, inverters, converters, etc.

What is the purpose of a diode?

Diodes are used in a circuit to ensure that the electrical current flows in one direction only. Due to this, they are used for converting AC to DC power.

1N4007 is one such diode, used in power supplies to prevent a negative voltage supply from causing problems in a circuit.

What are Rectifier Diodes?

1N4007 is a rectifier diode. Here’s what it means-

A rectifier diode is a semiconductor diode with higher current ratings, higher reverse voltage ratings, higher leakage current, and higher junction capacitance. Due to these parameters, these diodes are used in rectifier circuits for the conversion of AC to DC, and hence the name, rectifier diode.

From the construction point of view, these are solid-state devices made of semiconductor material that replaced vacuum valves for the rectification of the electrical signal.

What is the 1N400X Recifier Diode series?

The 1N400x series was originally introduced by Motorola’s Semiconductor Products Division registered at JEDEC in 1963 for military and industrial applications.

1N400x (1N4001 or 1N4000) series belongs to the family of 1 Ampere silicon rectifier diodes which are generally used in AC adapters for common household appliances. The blocking voltage ranges from 50 volts in 1N4001 to 1000 volts in 1N4007.

Here’s the table that shows the difference in their reverse voltage ratings:

1N400X DiodeReverse Voltage
1N400150 V
1N4002100 V
1N4003200 V
1N4004400 V
1N4005600 V
1N4006800 V
1N40071000 V
This table compares the Reverse voltage ratings of 1N400x Diodes

What does 1N in 1N400x represent?

The naming of 1NXXXX devices is based on the American standard numbering system. The standard is specific for semiconductor devices and now has been adopted globally. Here’s what 1N4007 means:

  • 1 means that it has 1 junction.
  • N signifies that it is a semiconductor diode.
  • 400X is the identification number to specify the diode.

So, 1N signifies that it is a single junction semiconductor. The model ranges from 1N4001 to 1N4007. The diodes in the 1N400X series have similar properties, so if the 1N4001 does not work for you, you can use 1N4002 as its substitute.
