STS11NF30L is a 30v N-channel Low gate charge STripFET? II Power MOSFET. The Power MOSFET STS11NF30L is the latest development of STMicroelectronic's unique "Single Feature Size?" strip-based process. The transistor STS11NF30L shows extremely high packing density for low resistance, rugged avalanche characteristics, and less critical alignment steps therefore a remarkable manufacturing reproducibility.
