The US05AWS-US05MWS series of high-efficiency surface-mount rectifier diodes utilizes a low-profile SOD-323 package, designed for automated assembly processes. They cover reverse voltage ratings from 50V to 1000V, support a continuous rectified current of 0.5A at a junction temperature of 125°C, and withstand 15A non-repetitive half-sine surges of 8.3ms.
Glass-passivated chip junction technology ensures high reliability, with a typical forward voltage drop of 1.0V and a reverse leakage current of only 5μA at the rated voltage of 25°C. Fast recovery characteristics achieve a maximum reverse recovery time of 75ns, which, combined with a typical junction capacitance of 8pF, significantly improves rectification and DC-DC conversion efficiency in switching power supplies.
The thermal resistance is 85°C/W based on a standard 5×5mm copper pad test, and the operating temperature range spans -55°C to 150°C. The entire series complies with EU RoHS directives, and its ultra-lightweight design of 0.054g and 1.4mm pad pitch maximizes PCB space utilization.
Certified to MIL-STD-750 military standard welding, it is suitable for half-wave rectification circuits with resistive or inductive loads. Capacitive load applications require a 20% current derating, providing a high-performance solution for industrial power systems, automotive electronic modules, and precision instruments.
