Recently, the well-known Japanese semiconductor manufacturer Rom (headquartered in Kyoto, Japan) has begun to mass-produce the world's smallest ※ size transistor package "VML0806" (0.8mm × 0.6) for small and light electronic devices such as smart phones and digital cameras. Mm, height 0.36mm).

This product has already started to sell samples (sample price is 80 yen/piece), and it has been put into mass production on a monthly basis of 60 million units since July. In order to meet the expanding market demand, we plan to further expand production scale in the future. In addition, the production base is located at ROHM-Wako Electronics (Malaysia) Sdn. Bhd. (Malaysia) and ROHM Integrated Systems (Thailand) Co., Ltd. (Thailand).

In recent years, in the portable device market including smartphones, the miniaturization and high performance of the whole machine have been rapidly developed, and the electronic components to be mounted have been increasingly demanded for miniaturization and thinning. However, in the conventional transistor package, there are problems such as miniaturization of the built-in components, stability of the solid crystal, and processing accuracy of the package, and there are technical problems in mounting, and therefore, 1006 size (1.0 mm × 0.6 mm, height) 0.37mm) is already the limit.

This time, ROHM successfully developed the world's smallest transistor package "VML0806" (0.8mm × 0.6mm, height 0.36mm) by developing small components and introducing high-precision package processing technology. Moreover, the external dimensions and external pin sizes have been optimized for better mounting performance and mass production.

The new package is first used in small signal MOSFETs. On the basis of maintaining the basic performance, compared with the small size 1212 package (1.2mm × 1.2mm, height 0.50mm) of the small signal transistor, the installation area is reduced by 67% and the thickness is reduced by 28%. In the future, ROHM plans to expand its application to a wider range of circuit applications such as bipolar transistors and digital transistors, which will help save space and density for various machines.

1) Realize the world's smallest size and greatly reduce the installation area

Compared with the smallest 1212 package (1.2mm × 1.2mm, height 0.50mm) of the small signal transistor, the mounting area is reduced by 67% and the thickness is reduced by 28%. As a transistor package has reached the world's smallest size.

2) Back side pins with high density mounting

3) Low on-resistance in MOSFET

Low on-resistance (2.6Ω) is achieved in the world's smallest size.
