The 1N4001 is a general-purpose silicon rectifier diode rated for 1 A continuous forward current and 50 V reverse voltage, ideal for low-voltage AC to DC conversion. It has a typical forward voltage drop of ~0.7–1.1 V and can handle up to 30 A surge current for short durations. With a recovery time suited to low-frequency rectification (50/60 Hz), it’s widely used in small power supplies, chargers, and protection circuits. Its DO-41 package ensures durability and easy PCB or through-hole mounting.
Proven Reliability In use for decades across consumer, industrial, and hobbyist electronics.
Versatile Application Range Handles 1 A continuous forward current and 50 V reverse voltage, making it perfect for small power supplies and rectifier bridges.
Rugged Construction DO-41 glass-passivated package resists heat and mechanical stress.
Good Surge Tolerance Can withstand 30 A surge current (8.3 ms), protecting against startup inrush.
Standardized Family Part of the 1N400x series (1N4001–1N4007), allowing easy voltage rating upgrades without changing footprint.
