STS8DNF3LL

Overview

The STS8DNF3LL is a dual N-channel Power MOSFET developed using STMicroelectronics’ STripFET II process. It features a 30 V breakdown voltage and an SO-8 package. The device provides a typical on-resistance of 0.017 Ohm and supports an 8 A current rating. Designed to minimize input capacitance and gate charge, it offers an optimal R DS(on) x Q g trade-off at 4.5 V. This configuration reduces both conduction and switching losses, making the component suitable for primary switching in advanced high-efficiency isolated DC-DC converters.
