RBR/RBQ, SBD Achieves Automotive AEC-Q101 Qualification
RBQ reduces the risk of thermal runaway, a characteristic of SBDs, by lowering IR.
ROHM Expands SBD Lineup to 178 with New Product Launches


ROHM announced on the 5th that it has developed 12 high-efficiency compact Schottky Barrier Diodes (SBDs) in the "RBR Series" and 12 in the "RBQ Series," suitable for circuit rectification and protection, expanding its SBD lineup to a total of 178 products. The RBR and RBQ series have improved performance by 25% compared to ROHM's existing products by introducing a new process.

The RBR series achieves low loss with its low VF (forward voltage) characteristics. The 12 new RBR models reduce the mounting area by 42% compared to existing products. The RBQ series features low IR (reverse current) characteristics, reducing the possibility of SBD thermal runaway. The 12 new RBQ models meet high-voltage requirements with 100 V specifications. Both series are AEC-Q101 compliant.

The 12 RBR products are suitable for onboard chargers, LED headlamps, car accessories, and laptops, while the 12 RBQ products are suitable for industrial power supplies, audio, laptops, xEVs, and engine ECUs. The 24 new products are in mass production starting in June, priced from 50 yen (excluding tax) per unit. Samples are available through online distributors such as Chip 1 Stop and CoreStaff.
