A 16 nC gate charge means a modest gate driver current — roughly 16 mA at 100 kHz switching — so the part is suited for medium-frequency SMPS and DC-DC converters without requiring a high-current driver. ## Temperature range and power dissipation This makes the STU7NF25 a candidate for harsh environments — motor drives, industrial power supplies, or downhole equipment where the ambient temperature pushes the junction above 125°C. No official second-source or successor is listed in the manufacturer's cross-reference; for dual-sourcing, a parametric search against 250 V, 8 A, TO-251 N-channel MOSFETs from other vendors would be the next step.","metaTitle":"STU7NF25 MOSFET, N-Channel 250V 8A, TO-251 IPAK","metaDescription":"STripFET™ II N-channel MOSFET, 250V Vdss, 8A continuous drain, 420mOhm Rds(on) at 10V.
