About the STMicroelectronics STFI Series

The STMicroelectronics STFI Series series groups 43 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common drive voltage (Max rds on, min rds on) of 10V, FET feature of - and FET type of N-Channel. Variants differ by case, current - continuous drain (Id) @ 25°C and drain to source voltage, so you can match the exact case your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current STMicroelectronics STFI Series variants and discontinued ones from a single page.
