The 1N4007 is a popular general-purpose silicon rectifier diode, widely used for converting alternating current (AC) to direct current (DC) in various electronic circuits and power supplies. It is known for its high reliability, low cost, and robust construction in a standard DO-41 axial-lead package.
Features
Rectification Function: The primary function is rectification, allowing current flow in only one direction (from anode to cathode) and blocking it in the reverse direction. High Voltage Rating: It has a maximum repetitive peak reverse voltage (VRRM) of 1000V, making it suitable for high-voltage applications. Current Handling: It can handle an average forward rectified current of up to 1A continuously and a non-repetitive peak forward surge current of up to 30A for a short duration. Low Forward Voltage Drop: The maximum forward voltage drop across the diode is typically around 1.1V at the rated current, minimizing power loss during conduction. Durable Package: It comes in a durable, epoxy-molded DO-41 axial package for through-hole mounting, with the cathode lead indicated by a clear polarity band. Wide Operating Range: The diode operates reliably across a wide junction temperature range, typically from -55°C to +150°C (or +175°C depending on the manufacturer). Low Leakage Current: It features a low reverse leakage current of approximately 5µA at the rated DC blocking voltage, which helps maintain circuit efficiency.
