New and improved tandem diodes from STMicroelectronics deliver economical alternative to silicon carbide
STMicroelectronics has unveiled its second generation of tandem diodes, which enable designers to cost-effectively enhance the energy efficiency of equipment such as power supplies, solar inverters, and e-transportation charging points.
Compared to first-generation devices, the new diodes have even lower reverse-recovery charge (QRR) to minimize switching losses, further extending their efficiency advantage over standard ultrafast diodes. The lower QRR also speeds up the fine-tuning of circuit designs, enabling faster time to market. Performance approaches that of silicon-carbide diodes, which are typically at least 30% more expensive.
