Ansas Releases SC02650A 650V/2A SiC SBD – SMA Package Enables High-Efficiency, High-Reliability Power Design
February 5, 2026Ansas

Ansas today announced the official launch of its new SC02650A 650V Silicon Carbide (SiC) Schottky Barrier Diode. Utilizing the industry-standard SMA package, this product combines high efficiency, low loss, and high reliability, offering a new high-performance solution for applications such as energy storage, electric drive, industrial control, and communication power supplies.

Based on Silicon Carbide material, the SC02650A features excellent high-temperature resistance. Even under extreme operating conditions of 175°C, its reverse leakage current remains stable at the microampere level, meeting the stringent reliability requirements of industrial-grade applications. Its forward voltage drop is as low as 1.20V, significantly reducing conduction losses and improving power conversion efficiency.

Regarding switching characteristics, the SC02650A exhibits the typical advantages of SiC devices: extremely low capacitive charge and nearly negligible reverse recovery current, greatly reducing dynamic losses during high-frequency switching. This makes it particularly suitable for high-switching-frequency application scenarios such as server power supplies, communication power supplies, and electric vehicle onboard chargers (OBC), contributing to enhanced overall system efficiency.

The electrical characteristics of the SC02650A are as follows:

  • 650V Reverse Voltage
  • Low Forward Voltage Drop, reducing conduction loss
  • Extremely Low Capacitive Charge (QC), supporting higher switching frequencies
  • Nearly Zero Reverse Recovery Time, significantly reducing switching loss
  • Excellent High-Temperature Operating Characteristics, suitable for harsh environments

Leveraging these advantages, the SC02650A can effectively improve system efficiency, reduce thermal design pressure, and maintain stable, reliable performance in high-frequency applications.

 

The product adopts the classic SMA package, which offers good mechanical strength and thermal cycle endurance. While maintaining excellent electrical performance, it achieves full compatibility with existing supply chains, production processes, and circuit layouts, providing a "seamless upgrade" solution for power electronic systems pursuing high efficiency and high reliability.

The SC02650A offers the following benefits:

  • High Versatility: Widely compatible with existing industry pad layouts
  • Low Layout Cost: No need for additional adaptation to new packages; can be directly applied to existing PCBs
  • Mature Supply Chain: Standardized device dimensions and processes facilitate system mass production

Suitable for Compact Designs: Enables efficient heat dissipation and high reliability within limited space

 

The SC02650A is suitable for the following application areas:

  • Photovoltaic and Energy Storage Inverters
  • OBC, DC-DC Converters
  • Industrial Servo Drives, Motor Controllers
  • High-Frequency Communication Power Supplies and Server Power Supplies

Its high-temperature stability, high-frequency low-loss characteristics, and robust package design provide strong support for system miniaturization, high efficiency, and reliable operation.

 

Ansas stated that the launch of the SC02650A marks a significant advancement in the company's SiC power device portfolio. The company will continue to expand its SiC product line, including devices with more voltage ratings, package types, and higher performance, to provide globally competitive, high-efficiency power solutions for customers.
