Discrete Semiconductor Devices - General-Purpose Devices
Aiming to expand overseas market share with high technological capabilities that contribute to product miniaturization
General-purpose devices are essential products which are used in every type of electric and electronic equipment regard-less of the market or application. ROHM’s general-purpose devices are a business which has continued from the early years of the company. Through our diverse portfolio consisting of products such as SBDs, TVSs, bipolar transistors, MOSFETs, FRDs, and RECs, as well as our high quality, minia-turization and high productivity technologies, and stable pro-duction capacity, we have gained a high degree of trust from customers and maintained a top-class market share for many years. In particular, we have secured an overwhelming share in the Japanese automotive market which requires a high level of quality and service.
In general-purpose devices, we lead the industry and believe that we can help reduce the environmental impact by efficiently using limited power and proposing small packages which allow space for component mounting. Furthermore, as the industry focuses on power devices, we will contribute to the development of the electric and electronic equipment market by continuing to supply the market in perpetuity.
Going forward, we believe that we need to expand the busi-ness by increasing our share in overseas markets and promot-ing a product strategy which is globally tailored to the appropriate quality and cost.

Toward the Realization of a Sustainable Society
Developing MOSFETs which realize a compact size and industry-leading*1 low power loss to contribute to high efficiency and the safe operation of small devices
In recent years, small devices have become more highly functional, and the component mounting space has decreased due to larger battery sizes for increased power requirements. Moreover, to efficiently use the limited battery power, the equipped components need to reduce power loss to a greater degree. To meet such requirements, ROHM developed the “RA1C030LD,” a compact and high-efficiency Nch MOSFET*2 with a 20V withstand voltage which is suitable for small and thin device switching. This new product adopts ROHM’s own wafer-level chip size package*3 to realize low power loss as well as miniaturization. It reduces power loss by up to roughly 20% more than general products with the same package and achieves an industry-leading power loss value which significantly contributes to high efficiency and a reduction in the substrate component area for various small devices. Going forward, ROHM will continue to help solve social issues such as reducing the environmental impact through the development of products that contribute to the high efficiency of small devices.
- *1 Researched by ROHM, as of November 10, 2022
- *2 Nch MOSFET A type of MOSFET which conducts when a positive voltage is applied to the gate with respect to the source. Because the drain-source ON resistance is smaller than with a Pch MOSFET, it can reduce the steady-state loss.
- *3 Wafer-level chip size package An ultra-compact package in which the formation of terminals and wiring are performed on the wafer which is then subse-quently divided into individual pieces.
