Description
This n-channel enhancement mode Power MOSFET is the latest refinement of STMicroelectronic unique "single feature sizeTM" strip-based process with less critical aligment steps and therefore a remarkable manufacturing reproducibility. The resulting transistor shows extremely high packing density for low onresistance, rugged avalanche characteristics and low gate charge.
