Product Description
The 1N5408 Rectifier Diode is a high-capacity silicon power diode designed for efficient AC-to-DC conversion and circuit protection. Rated at a robust 3A continuous current and a massive 1000V peak inverse voltage (PIV), it is the industrial "big brother" to the common 1N4007 series. Its large DO-201AD package allows it to handle significant power throughput with lower thermal resistance, making it ideal for battery chargers, bridge rectifiers, and high-voltage power supplies. The 1N5408 is a standard recovery diode, meaning it is optimized for 50Hz/60Hz mains rectification rather than high-frequency switching.
Key Features
High Current Handling: Supports up to 3A of continuous current, nearly three times the capacity of standard hobby-grade diodes.
Superior Voltage Protection: The 1000V PIV rating ensures the diode can safely block high-voltage spikes and back-EMF without breaking down.
High Surge Capability: Can withstand instantaneous current surges up to 200A, protecting the circuit during initial power-on or motor startup.
Low Leakage Current: Precision silicon construction minimizes reverse current flow, increasing overall efficiency in battery-sensitive applications.
Rugged Axial Construction: Features thick, high-conductivity leads and a flame-retardant epoxy case for reliable performance in industrial environments.
