STMicroelectronics announces a new series of 30V surface-mount power transistors


STMicroelectronics has introduced a new series of 30V surface-mount power transistors, achieving on-resistance as low as 2 milliohms (max) to increase the energy efficiency of products such as computers, telecom and networking equipment. Using its latest-generation STripFET VI DeepGATE process, which has high equivalent cell density, ST has achieved the industry’s best RDS(ON) in relation to active chip size. This is around 20 percent better than the previous generation and allows the use of small surface-mount power packages in switching regulators and DC-to-DC converters.


The technology also benefits from inherently low gate charge, which allows engineers to use high switching frequencies and thereby specify smaller passive components such as inductors and capacitors.
