Toshiba Introduce Junction Field Effect Transistor in World's Thinnest Lead-type Package

21 December, 2001

Tokyo--Toshiba Corporation today announced the world's thinnest junction field effect transistors (J-FET) in a lead package. Designed for incorporation in the microphone of mobile products, including cellular phones, the new J-FETs are almost 30 percent slimmer than typical J-FET products and will contribute to slimmer, sleeker personal digital equipment.

The trend in mobile phones is to folding models with a slimmer profile. Key to achieving this is a thinner electret condenser microphone, and manufacturers around the world are seeking to reduce the current typical thickness from 1.5mm to 1.3mm. Toshiba's new J-FET makes this possible.

The advance in cutting the transistor's height was not achieved at the cost of increased chip area. The package size of the new J-FET is the same as Toshiba's current product, 1.4mm x 1.2mm.
