About this deal

A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For use in general purpose rectification of power supplies, inverters, converters, and freewheeling diodes application.

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. For the current to flow from anode to cathode, the anode should be connected to a higher potential than the cathode(forward biasing). The current which flows from anode to a cathode terminal is known as a forward current. Reverse biasing will restrict the flow of current and can damage the device if voltage applied is greater than reverse breakdown voltage. During reverse biasing a leakage current flows through a diode which is negligible compared to forward current. Diode Configuration a b "SM4001-SM4007 Datasheet" (PDF). Diotec Semiconductor.

[11] [12] They are commonly used as rectifiers in AC adapters of electrical appliances to convert AC to DC, [13] and are also used in other types of power converters, [2] or as freewheeling diodes to protect circuits from inductive loads. [2] Besides, it can also be used in any general application where there is a need for a general diode. The 1N4007 diode is designed to operate with high voltages and can easily withstand voltages below 1000V. The average direct current of 1000mA or 1A, the 3W power dissipation, its small size, and low cost make it an ideal diode for a wide variety of applications. Datasheet" (PDF).

In addition to the reverse voltage, an essential characteristic is the forward current, for 1N4007 it reaches 1A. 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. 1N4007 Analogs Datasheet" (PDF).

This blog covers 1N4007 rectifier diode pinout, features, and other information including its advantages, applications and how to use this device, etc.

Replacement and Equivalent

Moreover it can also be used in any general purpose application where there is need of a general diode. The 1N4007 diode is built for working with high voltages and it can easily handle voltage below 1000V. The 1000mA or 1A average fwd current, 3W power dissipation with small size and lost cost also makes it ideal for wide variety of applications. Home power, Issues 21–32. Electron Connection, Ltd. 1991. p.173. A good generic diode for 1 A or less is the 1N4000 series devices. The breakdown voltage of the 1N4007 diode is around 1000 volts.
