SS54 Schottky Diode – 5A 40V High-Efficiency Rectifier (SMA Package)

Product Description:
The SS54 SMA Schottky Barrier Rectifier Diode is a high-efficiency, fast-switching power diode designed for low-voltage, high-frequency rectification. With a 40V reverse voltage rating and 5A average forward current, it delivers excellent performance in compact power systems such as DC-DC converters, power supplies, battery chargers, and polarity protection circuits.

Its low forward voltage drop (0.55V at 5A) helps reduce power loss and improve overall circuit efficiency, while the high surge current capability (150A) provides robustness against transient overloads. Built in a compact SMA (DO-214AC) surface-mount package, the SS54 ensures reliable operation, strong thermal stability, and easy integration into high-density PCB designs.

This Schottky rectifier's combination of high current capability, ultra-fast switching, and low leakage current makes it a popular choice for both industrial and consumer electronic applications.
