ROHM unveil the industry's smallest transistor package
News Release from:
18 October 2012
ROHM has developed the smallest transistor package on the market optimized for thin, compact portable devices. The VML0806 measures just 0.8mm×0.6mm, with a height of only 0.36mm. As portable devices such smartphones and digital cameras get smaller and more sophisticated, thinner, more compact components are required.
However, until now, problems related to internal element miniaturization, bonding stability, package process accuracy, and surface mount technology limit the smallest conventional transistors to the 1006 size (1.0mm×0.6mm, t=0.37mm).
ROHM was able to overcome these challenges by utilizing a smaller element and high-precision package process technology, resulting in an unprecedentedly compact form factor. In addition, optimized external and terminal dimensions improve mountability while facilitating mass production.
ROHM will initially offer this new package for small-signal MOSFETs, reducing mounting area and thickness by 67% and 28%, respectively, compared with conventional 1212-sized (1.2mm×1.2mm, t=0.5mm) products while still maintaining characteristics and performance. Future implementations will include bipolar and digital transistors, which are expected to contribute to end-product miniaturization and higher-density designs for circuit applications of all types.
