ROHM unveils smallest Zener diodes in ultra-compact 0402 format

The ultra-compact form factor (0.4 x 0.2 mm) contributes to increased miniaturization and sophistication in devices requiring greater compactness and minimal thickness, including mobile phones and digital cameras.

In recent years, the increasing sophistication and functionality of smartphones requires a greater number of components, necessitating ultra-compact parts that support high-density mounting to maintain or even decrease overall set size. Although passive products such as resistors and capacitors are already available in the 0402 size, the smallest discrete products, including transistors and diodes, offered until now are in the 0603 size due to the relatively increased complexity.

In October of 2011 ROHM introduced the smallest chip resistors on the market, in the 03015 size, which represented a significant breakthrough. The same proprietary ultra-precision technology was used for diode production, along with an original chip device structure and ultra-fine process technology, resulting in an ultra-compact, ultra-thin form factor that maintains the same electrical characteristics as conventional 0603-size products.

ROHM will first offer Zener diodes in the 0402 size, then expand to include Schottky barrier diodes and other diode products.


Samples are now available. OEM quantities will be available as of April 2013
