Onsemi 1N4001G: General-Purpose Rectifier Diode for Power Supply and Conversion Circuits

The Onsemi 1N4001G is a widely used general-purpose rectifier diode designed for power supply and conversion applications. As part of the popular 1N400x series, this diode offers reliable performance in converting alternating current (AC) to direct current (DC), making it a fundamental component in various electronic circuits.

With a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 50 V, the 1N4001G is well-suited for low-voltage power supplies, adapters, and battery chargers. Its robust construction ensures efficient operation in environments where surge currents and transient voltages are common. The diode’s low forward voltage drop minimizes power loss, enhancing overall circuit efficiency.

The 1N4001G is also designed for easy integration into printed circuit boards (PCBs), thanks to its axial-lead package. This makes it ideal for both prototyping and mass production. Additionally, its ability to withstand high surge currents—up to 30 A—ensures durability in demanding applications like industrial power systems and automotive electronics.
