STripFET™ Series V Power MOSFETs

Low voltage MOSFETs from STMicroelectronics are critical contributors to the efficiency of switching topologies

STMicroelectronics' low voltage MOSFETs are critical contributors to the efficiency of switching topologies used in DC/DC converter and motor control applications. For example, with a synchronous buck converter, the major contributions to the losses in high frequency switching are switching losses in the high side (H-S) FET (control FET) and conduction losses in the low side (L-S) FET (sync FET). ST's STripFET V technology has one of the best switching figures of merit (RDS(on) * Qg) and thus, is ideal for H-S. Additionally, the STripFET VI DeepGATE™ has one of the lowest RDS (on) values per area and thus, is better for L-S. ST offers a series of 30-volt (H5 and H6) and 40-volt (F5 and F6) FETs in PowerFLAT™ packages to combine the features of the latest STripFET technologies for H-S and L-S combinations with the improved power density and thermal capability of PowerFLAT packaging.
