1N4007

The 1N4007 is a common rectifier diode manufactured by Taiwan Semiconductor, housed in a DO-41 (DO-204AL) package. This component is essential for converting alternating current (AC) into direct current (DC), functioning as a one-way valve for electrical current. Its design makes it a reliable choice for numerous electronic devices and power supply systems.

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

The diode's physical dimensions are approximately 5.2 mm in body length and 2.7 mm in diameter. The unmarked lead serves as the anode, and the lead with a silver band is the cathode, with current flowing from anode to cathode. Its thermal resistance is typically 50 °C/W, requiring consideration for heat dissipation in PCB layout.

This rectifier is a fundamental component in power supplies and general electronics, providing unidirectional current essential for component operation. Its cost-effectiveness and ease of implementation contribute to its widespread use in hardware projects.
