1N4007 Diode
1N4007 Diode
Pack of 10
The 1N4007 is a standard rectifier diode, designed for general-purpose use in a variety of applications. It is a vital component in many electrical and electronic circuits, serving as a fundamental building block for rectification, switching, and voltage regulation.
The primary function of the 1N4007 diode is to allow current to flow in one direction while blocking it in the other direction. This unidirectional current flow is due to the diode's inherent property of having a low resistance in the forward direction (anode to cathode) and a high resistance in the reverse direction (cathode to anode).
The 1N4007 diode can withstand a maximum peak reverse voltage of 1000V, making it suitable for high-voltage applications.
The diode has a maximum average rectified current rating of 1A, allowing it to handle moderate to high currents in various circuits.
The diode's reverse leakage current is relatively low, ensuring minimal current flow in the reverse direction.
The forward voltage drop of the diode is approximately 1.1V, which is typical for standard rectifier diodes.
The 1N4007 diode can operate within a wide temperature range, making it suitable for use in various environmental conditions.
