The 1N5399 General Purpose Rectifier Diode is a standard silicon diode designed for efficient rectification and voltage blocking in a variety of electronic applications. With a maximum repetitive reverse voltage (Vrrm) of 1000V and a forward current (If) rating of 1.5A (with a surge capability of up to 50A for 8.3ms), it’s perfect for converting AC to DC in power supplies, battery chargers, and high-voltage circuits. Encased in a DO-15 (DO-204AC) axial package, the 1N5399 features a low forward voltage drop of approximately 1.1V at 1.5A and a fast recovery suitable for general-purpose use. Its rugged construction offers a power dissipation of 3W and operates within a temperature range of -55°C to 150°C. This RoHS-compliant diode is widely used in DIY electronics, appliance repairs, and industrial applications requiring reliable high-voltage performance. Its axial leads are solder able per MIL-STD-202 standards, and the cathode is marked with a color band for easy identification.
