ROHM Introduces Smallest Zener Diodes

ROHM announced the development of its claimed smallest Zener diodes in the industry ideal for high-density mounting in portable devices such as smartphones. Size is reduced by 55% over conventional 0603-size (0.6x0.3mm) products. The ultra-compact form factor (0.4x0.2mm) 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.

Key Features

* Original process technology results in the industry's smallest package size: 0402 (0.4mmx0.2mm)

* Dimensional precision improved significantly, from ±20µm to ±10µm

* Gold electrode surface enhances solder wettability and reliability

Availability

Samples are available, OEM quantities will be available as of April 2013
