In the Core Operation of Electronic Devices

The performance of rectifiers directly impacts system stability, energy efficiency, and cost control. However, traditional rectifiers generally suffer from three major pain points: severe EMI interference, low efficiency, and poor thermal management. Excessive EMI may cause devices to fail EMC certification; inefficient operation increases energy consumption costs; and thermal runaway triggers the risk of malfunctions. These issues not only drive up production costs but also undermine the market competitiveness of products.

To address these industry pain points, Heketai Electronics has launched the RABS210 Soft-Bridge Rectifier based on technological innovation. With advanced soft recovery technology, high-efficiency design, and full-lifecycle cost optimization, it provides a high-performance rectification solution for the electronics industry.

Advanced Soft Recovery Technology: Suppressing EMI Interference at the Source

The EMI interference of traditional rectifiers stems from the high di/dt (current change rate) of reverse recovery current, which requires the additional installation of EMI filters—this not only increases costs but also complicates the design. The RABS210 adopts advanced soft recovery technology. By optimizing the doping distribution and structural design of the diode, the reverse recovery process becomes smoother, reducing the di/dt of reverse recovery current by more than 30% and lowering the EMI interference intensity by 20-30dBμV across all frequency bands (with particularly significant effects in the frequency band below 500kHz). It can easily pass EMC certification without the need for additional EMI filters, greatly simplifying the design process and reducing BOM costs.

Low Forward Voltage Drop + Soft Recovery: 3-5% Improvement in System Efficiency

The high forward voltage drop (usually ＞1.5V@2A) and hard recovery characteristics of traditional rectifiers lead to high conduction losses and switching losses. The RABS210 reduces the forward voltage drop to 1.3V@2A by optimizing the chip structure (a 15% reduction compared to traditional products). At the same time, the soft recovery technology reduces switching losses, improving the overall system efficiency by 3-5%. In scenarios sensitive to efficiency, such as fast-charging power supplies and photovoltaic systems, this advantage can be directly translated into lower energy consumption costs. Taking a 100W fast-charging power supply as an example, the annual operating energy consumption can be reduced by approximately 12%.

Full-Lifecycle Cost Optimization: Balancing Reliability and Economy

Although traditional rectifiers seem to have a low unit price, additional costs are required for EMI filters, heat dissipation design, etc. Moreover, low efficiency and high failure risks drive up long-term operating costs. The RABS210 achieves multiple cost optimizations through integrated design:

• BOM Cost: Reduces EMI filter components, lowering costs by 10-15%.
• Design Cost: Compact packaging (compatible with mainstream mounting processes) saves 30% of PCB space and simplifies layout design.
• Energy Consumption Cost: A 3-5% improvement in efficiency reduces annual energy consumption costs by 8-12%.
• After-Sales Cost: The reverse recovery time is as short as 500ns, the surge current withstand capacity reaches 10A (2ms), and the built-in heat dissipation structure reduces the risk of thermal failure. Reliability is improved by 40%, and after-sales costs are reduced by 25%.

Conclusion

Heketai's RABS210 Soft-Bridge Rectifier breaks through the performance bottlenecks of traditional rectifiers through technological innovation, meeting the needs of various fields such as communication equipment, consumer electronics, fast-charging power supplies, and photovoltaic systems. In the future, Heketai will continue to deepen the R&D of rectifier technology and provide products with higher performance and better cost-effectiveness to help the electronics industry achieve the upgrading goals of "high efficiency, reliability, and energy conservation".
