At the high end, the 420 mOhm Rds(on) doubles per the normalised curve — the designer must derate the continuous drain current from 8 A at 25°C case to roughly 4 A at 150°C junction to stay inside the SOA.","metaTitle":"STD8NF25 N-Channel MOSFET, 250 V, 8 A","metaDescription":"STripFET™ II N-channel MOSFET, 250 Vdss, 8 A continuous drain, 420 mOhm Rds(on) at 10 V.
