The 1N4001 is a widely used general-purpose rectifier diode, commonly employed in various electronic circuits for converting alternating current (AC) to direct current (DC).

Here's a breakdown of its key specifications:

Type: The 1N4001 is a rectifier diode, specifically designed for rectifying AC voltage to produce DC voltage.

Power Dissipation: It is capable of handling up to 1 watt of power dissipation under normal operating conditions.

Voltage Rating: The maximum repetitive peak reverse voltage (VRRM) for the 1N4001 is 50 volts. This indicates the maximum voltage it can withstand in the reverse-biased direction without breaking down.

Forward Current: It has a maximum average forward rectified current (IF(AV)) of 1 ampere, making it suitable for low to moderate power applications.

Forward Voltage Drop: When conducting current in the forward direction, the voltage drop across the diode is typically around 0.7 volts.

Package Type: The 1N4001 is available in through-hole packages, typically with axial leads, for easy mounting onto circuit boards.

Construction: Like most rectifier diodes, the 1N4001 is constructed using silicon semiconductor material, providing good electrical properties such as low forward voltage drop and high reverse voltage blocking capability.


The 1N4001 is commonly used in power supplies, battery chargers, voltage regulators, and rectifiers in various electronic devices and circuits.

Temperature Range: It is designed to operate over a wide temperature range, typically from -65°C to +175°C, ensuring reliability under different environmental conditions.
