TVS Diodes (ESD Protection Devices)Proposal for Miniaturization of TVS Diodes

Murata has lineup of 0603 (mm) and 0402 (mm) TVS Diodes, enabling the issue of insufficient mounting area to be resolved. If you experience any trouble concerning the handling of small devices, please feel free to consult us concerning mounting technology.

[Is there anybody who is inconvenienced by one of the following situations?]

The available mounting space is restricted, and the components currently used do not fit on the board.
We want to mount small components, but trouble keeps occurring, and we have no in-house know-how, so we do not know what to do.

Outline of case example

Murata makes use of its technology fostered through the development of laminated ceramic capacitors and inductors, and also develops small TVS Diodes.
Along with the miniaturization of mobile devices, the size requirements placed on TVS Diodes are also becoming increasingly severe. Murata has a lineup of small devices to meet the needs of customers.

LGA mounting technology support

When a small component is being mounted, problems such as deviation of the product from the land, tilting of the component with respect to the board, and oozing of solder in the sideways direction occur frequently.
Murata makes proposals concerning the recommended land pattern and also provides support for evaluating the mounting condition, so that we can provide follow-up to the best of our ability and thereby enable our customers to correctly mount components.
