The STripFET III family has been superseded by later generations (STripFET F7, MDmesh), but none carries a guaranteed pin-to-pin replacement in the I2PAKFP full-pack package. If you need a drop-in fit, the replacement search should start with the same package code (I2PAKFP / TO-281) and the same 100V / 46A class from ST's current portfolio. ## 100V, 46A, 9.6 mOhm — sizing the part for the rail The 100V rating gives comfortable margin on a 48V bus or a 12V/24V rail with inductive load transients — you are not living at the edge of the SOA. The 46A Id figure is the package-and-die thermal limit at Tc=25°C; real-world current in a 70°C ambient, through a heatsink, will be lower, but the headline number tells you this die is sized for a 30A–40A continuous load with adequate heatsinking. The on-resistance is 9.6 mOhm maximum at 23A with 10V gate drive. That is the number to use for conduction-loss calculations at full load. At 23A, the dissipation is roughly 5W (I²R) before switching losses — within the 35W package power limit, but the junction temperature rise from that alone is significant. The 57 nC gate charge at 10V is modest for a 46A device, so the gate driver does not need to be oversized; a standard 1A–2A driver handles the switching edges cleanly. Input capacitance is 3305 pF at 25V Vds. That is a moderate figure — the Miller plateau will be visible but not problematic with a properly laid-out gate loop. Keep the gate-driver return path short and the gate resistor sized for the desired turn-on speed. ## TO-262 full-pack I2PAKFP — the package that saves an insulator The STFI130N10F3 comes in a TO-262-3 Full Pack, also called I²Pak or I2PAKFP (ST's designation TO-281). That saves assembly time and improves thermal transfer. The trade-off is slightly higher thermal resistance compared to a standard TO-220 with an insulator, but for a 35W dissipation ceiling it is adequate with a modest heatsink. The gate threshold is 4V maximum at 250µA drain current. That is a standard threshold for a 10V-driven device — do not expect it to turn on hard with 5V logic. That is the full industrial-plus grade — suitable for engine-bay electronics, industrial motor drives running hot, and outdoor telecom equipment where ambient can hit 85°C and the junction climbs from self-heating. The 175°C Tj max is the same rating as automotive-grade MOSFETs, though this part does not carry an AEC-Q101 line item in the record.","metaTitle":"STFI130N10F3 STMicroelectronics N-Channel MOSFET","metaDescription":"STFI130N10F3 is an obsolete N-channel STripFET III MOSFET rated 100V Vdss, 46A Id, 9.6mOhm Rds(on) at 10V.
