Diodes' Silicon Carbide Schottky Diodes Offer Industry-Leading FoM and System Efficiency

Diodes Incorporated (Nasdaq: DIOD) announced the expansion of its silicon carbide (SiC) product portfolio with the introduction of five high-performance, low quality factor-of-mass (FoM) 650V silicon carbide Schottky diodes. The DSCxxA065LP series, with current ratings of 4A, 6A, 8A, 10A, and 12A, is available in the ultra-high thermal efficiency T-type DFN8080-4 package and is designed for high-efficiency power switching product applications such as DC-to-DC, AC-to-DC, renewable energy, data centers (especially those dealing with artificial intelligence computing), and power supplies. The DSCxxA065LP series is available in 4A, 6A, 8A, 10A, and 12A current ratings in an ultra-high thermal efficiency T-type DFN8080-4 package, and is designed for high-efficiency power switching applications, such as DC to DC, AC to DC, renewable energy, data centres, especially those handling large amounts of artificial intelligence computing, and industrial motor drives.

The DSCxxA065LP series has the best quality factor (FoM = QC × VF) in the industry, thanks to the following two features:

• No reverse recovery current and low capacitive charge (QC), resulting in negligible switching losses;
• Low forward voltage (VF), which significantly reduces conduction losses and improves overall power efficiency.

These two features make this series ideal for high-speed switching circuits.

The DSCxxA065LP series also has a lower reverse leakage current (IR) than the rest of the industry, with a maximum of 20 µA, which significantly reduces thermal dissipation and conduction losses, and improves system stability and reliability compared to silicon-based Schottky devices. Lower thermal dissipation also reduces cooling costs and operating expenses.

The small, lightweight T-DFN8080-4 (typical size: 8mm x 8mm x 1mm) surface mount package has a large heat sink on the bottom to reduce thermal resistance, and the T-DFN8080-4 takes up less board area but has a larger heat sink, making it a perfect replacement for TO252 (DPAK). These two features help increase the power density of the circuit design, reduce overall size, and lower the cooling budget.       

The DSC04A065LP (4A), DSC06A065LP (6A), DSC08A065LP (8A), DSC10A065LP (10A), and DSC12A065LP (12A) can be ordered in units of 2,500.
