Industry’s Smallest 4A and 5A Schottky Rectifiers
Set New Benchmarks in Current Density

The DIODES™ SDM5U45EP3 (5A, 45V), DIODES™ SDM4A40EP3 (4A, 40V), and DIODES™ SDT4U40EP3 (4A, 40V) Schottky rectifiers achieve the industry’s highest current densities in their class, addressing market demands for smaller and more powerful electronic systems.
The SDT4U40EP3 is the industry’s smallest 4A trench Schottky rectifier, being the first ever in a 1608 package. It takes up >90% less PCB area, and together with its slim off board profile, occupies <2% volume than competing SMA packaged devices. Its 800A/cm2 current density, also the highest in the industry for a trench Schottky, is thanks to the patent-pending innovative cathode design and manufacturing processes utilized. The resulting ultra-low forward voltage performance (0.47V typical) minimizes power losses, enabling the design of higher efficiency systems. Furthermore, its superior avalanche capability makes it robust enough to deal with extreme operating conditions such as transient voltages.

The DIODES™ Advantage
Small form-factor CSP Schottky rectifiers provide the highest
current density and maximize board real estate.
