1N4007

The 1N4007 is a widely used rectifier diode manufactured by FAGOR, housed in a compact DO-41 (DO-204AL) axial package. This component functions as a one-way valve for electrical current, converting alternating current (AC) into direct current (DC), making it essential for numerous power supply systems and electronic devices.

Key electrical specifications include an average rectified current of 1.0 A and a peak repetitive reverse voltage (VRRM) of 1000 V. It also offers a peak forward surge current rating of 30 A for short durations (8.3 ms), crucial for handling inrush currents during system startup. The maximum forward voltage (VF) is 1.1 V, and it operates within a junction temperature range of -55 to +150 °C.

The DO-41 package is a small black cylinder with two metal axial leads, where the unmarked lead is the anode and the lead with a silver band is the cathode. Current flows from anode to cathode. Its physical dimensions are approximately 5.2 mm in body length and 2.7 mm in diameter. Designers should consider the typical thermal resistance of 50 °C/W when planning PCB layouts to ensure adequate heat dissipation, as a 1-watt power dissipation can raise the junction temperature significantly above ambient.

This diode is a cost-effective and reliable choice for many hardware projects requiring unidirectional current flow. Its silicon junction is easy to implement in various circuit designs.
