1N4007

The 1N4007 is a common rectifier diode manufactured by Diodes Incorporated, housed in a DO-41 (DO-204AL) package. This diode functions as a one-way valve for electrical current, converting alternating current (AC) into direct current (DC), which is essential for many electronic devices and power supply systems.

Key electrical specifications include an average rectified current of 1.0 A and a peak repetitive reverse voltage (VRRM) of 1000 V. It also has a maximum forward voltage (VF) of 1.1 V and a peak forward surge current (IFSM) rating of 30 A for 8.3 ms, making it suitable for handling startup inrush currents. The operating junction temperature range is from -55 °C to +150 °C.

The DO-41 package is a small, axial-leaded cylinder. The anode is the unmarked lead, and the cathode is indicated by a silver band. Current flows from anode to cathode. Its compact physical dimensions, typically 5.2 mm in body length and 2.7 mm in diameter, facilitate integration into various circuit designs.

With its ability to handle high voltages, low manufacturing cost, and ease of implementation, the 1N4007 remains a popular choice for general-purpose rectification in hardware projects and power supply applications.
