The SD400R16PC is a high-power stud-mounted rectifier diode, ideal for industrial rectification. In a reverse polarity DO-9 ceramic package, it handles 400A average forward current (up to 480A at 100°C) and 1600V repetitive peak reverse voltage. Key specs include 1.62V max forward drop at 1500A surge, 8640A non-repetitive surge capability, and -40°C to 190°C operation.

Features: robust compression-bonded design, 3/4"-16 UNF thread mounting (27 Nm torque), and 250g weight.

Applications: Power supplies, motor drives, machine tools, welding equipment, inverters, and traction systems in EVs/rail. Excels in high-surge, thermally demanding environments.
