Diode 1N4001 (1A-50V)

The Diode 1N4001 (1A-50V) is the 50V member of the classic 1N400x rectifier family, in a through-hole DO-41 package. It is a good fit for low-voltage DC circuits, reverse-polarity protection and flyback protection in Arduino and hobby projects.

Diode 1N4001 (1A-50V) – Key Features

• Part number: 1N4001
• Package: DO-41, through-hole axial
• Average forward current: 1A
• Reverse voltage: 50V
• Forward voltage: about 1.1V at 1A

Applications

Makers, students and technicians use it in many kinds of projects, for example:

• Reverse-polarity protection
• Flyback diode across relays and small motors
• Low-voltage rectification
• Blocking diode in battery circuits
• Repair of electronic boards

Usage Tips

The silver band marks the cathode. Only use the 1N4001 where the reverse voltage stays below 50V; for mains or higher voltages use the 1N4007.
