ROHM Develops Small Transistor with 20% Lower Power Consumption

Update time : 2023-01-05 09:51:33

December 27 - ROHM Corporation, one of the world's leading semiconductor manufacturers, is the first Japanese company to enter Silicon Valley in the United States. Rohm has now developed a small transistor that consumes 20 percent less power than before, according to the Nikkei business daily.

Compared with conventional transistors, this small transistor uses the original TDACC circuit design technology to reduce power loss by 20%. it is expected to be used in wearable devices such as wireless headphones and watch terminals, and the company will initially produce 10 million units per month, IT House learned that this semiconductor can efficiently switch the current on and off even if the total length is only 1 mm.
The transistor is said to be close to the smallest size, 1 mm long and 0.6 mm wide, and is mainly used for switching the power required for switching electronic parts and sensor types inside wearable devices, etc.
Compared with the same size of the general product, the new small transistor uses 20% less power loss. Transistors are difficult to reduce both "on-resistance" and "switching losses," but Rohm has succeeded in doing so using large-scale integrated circuit (LSI) technology. The silicon substrate is not covered with resin, but coated with an autonomous insulating film to achieve miniaturization.
Officials say that this transistor can be used for headphones in two to four per product, which also can significantly reduce the space occupied by electronic circuits.
