1N4001 vs 1N4007: What’s the Differences?

A 1N4001 is a diode of the 1N400x series, all diodes of this series are widely used in electronic devices.

The 1N4001 diode is manufactured with good specifications, such as 1A upstream current, 3W power dissipation, and small in size with low price, which makes it ideal for a wide variety of electronic applications.

1N4007 is a PN junction rectifier diode. These types of diodes only allow the flow of electric current in one direction. Therefore, it can be used for the conversion of alternating current to direct current. The 1N4007 is electrically compatible with other rectifier diodes and can be used instead of any diode of the 1N400X series.

The 1N4007 has various applications in real life. For example, applications of freewheeling diodes, general rectifying of power supplies, inverters, converters, etc.

Just shown below, The 1N4007 and 1N4001 both have two pins, the anode, and cathode respectively. Both pins have opposite charges on them. The two pins and their names and charges are shown in the table below.

The 1N4007 and 1N4001 diodes have a cathode (-) and anode (+). In the schematic symbol, the tip of the triangle with the line on top of it is the cathode.

1N4001 series diodes are 1 Ampere current handling general purpose rectifier diodes. 1N stands for American standard semiconductor (Generic name) with ONE JUNCTION.

400X Series like 4001, 4002 to 4007 indicate the diodes' voltage, current, and power rating.

1N= Means One Junction between P-type and N-Type.

400= Means the Serial number of the rectifier.

1= Means Defines its (1 A) current rating.

To obtain the maximum operating time of the diode, it is recommended to stay between 30 and 40 V below its maximum repetitive reverse voltage and other values. Always connect with correct polarity, and do not exceed a load of 1A. Do not operate and store at a temperature below -55 centigrade and above +175 centigrade.
