That saves a BOM line and a manual assembly step, and it eliminates the thermal resistance of the interface pad. ## 235 mOhm Rds(on) and 18 nC gate charge — conduction and switching budget At 14 A the Rds(on) will be higher — the datasheet curve shows the normalised increase with current and junction temperature — so the designer should budget around 300 mOhm hot for the worst-case conduction loss. Input capacitance is 680 pF at 25 V drain-source. That is a moderate figure — the gate-drive rise time will be a few tens of nanoseconds with a typical driver, so the part is well suited for hard-switched topologies like flyback converters, PFC boost stages, and two-switch forward converters in the 50–150 kHz range. For a production BOM this means no urgent obsolescence risk — the part can be qualified into a new design with confidence that the supply channel will remain open for the foreseeable future.","metaTitle":"STF16NF25 N-Channel MOSFET 250V 14A TO-220FP STripFET II","metaDescription":"STF16NF25 N-channel 250V 14A MOSFET in TO-220 Full Pack. 235 mOhm Rds(on) at 10V, 18 nC gate charge.
