Increased performance from new series of Schottky diodes

Using an advanced deep-trench process, the SDT series of Schottky diodes introduced by Diodes Incorporated delivers superior performance at similar or lower cost to planar-type Schottky diodes. The family of 29 devices, housed in thermally-efficient packages, provides the blocking, free-wheeling, flyback and other diode functions commonly found in a wide range of applications, such as AC/DC chargers/adapters, DC-DC up/down conversion, and AC LED lighting. The company’s innovative deep-trench process enables the SDT series of Schottky diodes to achieve a VF as low as 0.62V along with a leakage current of just 3.5µA. This exceptional performance results in outstanding power efficiency and contributes to smaller form-factors for end-system designs. Within the family, maximum average rectified current ratings from 5A to 40A are offered, with peak repetitive reverse voltages (VRRM) up to 120V and forward surge currents (IFSM) as high as 280A, ensuring robust system operation across the full temperature range. PowerDI5, TO220AB, and ITO220AB package options all offer excellent thermal transfer properties that allow the new series Schottky diodes to perform reliably in demanding applications. These packages are well-suited for high-volume manufacturing and also allow the SDP parts to be used as drop-in replacements for generic planar-type Schottky diodes.
