Santa Clara, CA and Kyoto, Japan, Nov. 02, 2021 (GLOBE NEWSWIRE) — ROHM Semiconductor at present introduced its expanded portfolio of Schottky barrier diodes (SBDs) with 24 new compact, excessive effectivity fashions (12 RBR collection and 12 RBQ collection). These gadgets – 178 in complete – are perfect for safety and rectification circuits in automotive, industrial tools, and client purposes.
Diodes are generally utilized in a range of circuits for rectification and safety. Moreover, as decrease energy consumption is required in most purposes, the adoption of SBDs – that are extra environment friendly than different diodes – is on the rise. However, if VF is lowered to enhance effectivity, IR (which is inversely associated to VF) will develop into greater. This will increase the chance of thermal runaway, so you will need to stability each VF and IR when deciding on SBDs for circuit design.
In response, ROHM has strengthened its lineup of SBDs that balances small measurement with low VF and IR – traits demanded by the automotive sector. The market-proven RBR and RBQ collection have been additional expanded to incorporate a lineup of compact, excessive present, excessive voltage merchandise that allow rectification and safety in a wider vary of purposes.
Introducing a brand new course of permits ROHM to enhance the chip efficiency of each collection by 25% (VF of the RBR collection specifically) over ROHM’s typical merchandise. Furthermore, the RBR collection options wonderful low VF traits – key to bettering effectivity and decreasing loss. This makes them ideally suited for automotive purposes, in addition to client electronics equivalent to laptops the place excessive effectivity is required. In reality, 12 of the merchandise undertake a compact package deal (PMDE package deal) that reduces mounting space by 42% in comparison with present merchandise (PMDU package deal).
At the identical time, the RBQ collection delivers wonderful low IR traits that allow secure operation in excessive temperature environments – considerably decreasing the chance of thermal runaway which is a priority with SBDs. As such they are perfect for automotive powertrain purposes and energy provides for industrial tools that function in excessive temperature environments. 12 new 100V merchandise have been added to satisfy the necessity for greater voltages, and each collection are certified underneath the AEC-Q101 normal to make sure automotive-grade reliability.
Going ahead, ROHM will proceed to enhance the traits and effectivity of its semiconductor gadgets, from low- to high-voltage merchandise, whereas strengthening its distinctive lineup to additional cut back energy consumption and obtain higher miniaturization of purposes.
