Diodes Incorporated SDT/SDM Schottky Rectifiers

Featuring ultra-compact chip scale packages (CSPs)

The DIODES™ SDM5U45EP3 (5A, 45V), SDM4A40EP3 (4A, 40V), and SDT4U40EP3 (4A, 40V) achieve the industry’s highest current densities in their class, addressing market demands for smaller and more powerful electronic systems.

Each device can be employed for a variety of different purposes, serving as blocking or reverse-polarity protection diodes, electrical over-stress protection diodes, and free-wheeling diodes. The rectifiers in this series are designed for use in space-constrained applications - such as portable, mobile, and wearable devices, as well as IoT hardware.

With a 2mm2 footprint, this rectifier enables system designers to maximize board real estate in modern and highly integrated consumer products. They also feature greater power dissipation which reduces BOM costs and increases reliability.

These two devices feature a 1.28mm2 footprint which is classified as an ultra-thin CSP that results in shortened thermal paths.

All rectifiers are environmentally-friendly devices and fully RoHS 3.0 compliant with no exemptions.
