1N4007

The 1N4007 is a diode rectifier manufactured by GS, commonly used in electronic devices to convert alternating current (AC) into direct current (DC). It functions as a one-way valve for electrical current, allowing flow in a single direction.

This diode is housed in a DO-41 package, a small black cylinder with axial leads. It has an average rectified current rating of 1.0A and a peak repetitive reverse voltage of 1000V. The maximum forward voltage is 1.1V. Its typical thermal resistance is 50 °C/W, with an operating junction temperature range of -55 to +150 °C.

The 1N4007 is a popular choice for many hardware projects due to its ability to handle high voltages, low manufacturing cost, and ease of implementation. Its silicon junction is straightforward to integrate into circuits. The peak forward surge current rating of 30A is important for handling inrush currents during system startup, such as when power supply filter capacitors are initially charged.

Designers should consider the thermal resistance when planning PCB layouts, ensuring adequate copper area for heat dissipation. The component's physical dimensions are approximately 5.2 mm in body length and 2.7 mm in diameter.
