Onsemi 1N5402RLG: General-Purpose Rectifier Diode for Power Supply Applications

The Onsemi 1N5402RLG is a highly reliable, industry-standard rectifier diode designed to serve as a fundamental component in a wide array of power supply circuits. As part of the popular 1N540x series, this device is engineered to handle significant power levels, making it an ideal choice for applications requiring efficient AC to DC conversion.

This diode is characterized by its robust construction and high current capability, featuring a maximum average forward rectified current of 3.0 Amperes. This makes it exceptionally suitable for power supplies, adapters, and battery chargers where such current levels are commonplace. A key attribute of the 1N5402RLG is its ability to withstand high reverse voltages, with a peak repetitive reverse voltage (V_RRM) of 200 Volts. This ensures reliable operation and protection against voltage spikes in the circuit, enhancing the overall durability of the end product.

Furthermore, the diode boasts a low forward voltage drop, which contributes to improved energy efficiency and reduced heat generation within the system. Its construction is optimized for surge handling, capable of managing non-repetitive peak surge currents up to 200 Amperes. This surge resilience is critical for enduring initial inrush currents often encountered during power supply startup.

Housed in a durable, lead-forming molded plastic package, the 1N5402RLG is designed for easy automated insertion on printed circuit boards (PCBs), streamlining the manufacturing process for high-volume production. Its versatility extends beyond traditional power supplies to include use in inverters, converters, and as general-purpose rectification in various industrial and consumer electronic equipment.
