Product details

Obsolete — last-time-buy sourcing for sustainment programs

100 V, 40 A N-channel with 10 mOhm Rds(on)

Gate charge is 45 nC at 10 V, and input capacitance measures 3100 pF at 50 V Vds, giving a reasonable switching figure of merit for hard-switched topologies up to the 100 kHz range.

TO-220FP — fully isolated tab, no extra insulator needed

The TO-220 Full Pack (TO-220FP) package has a fully molded backside, so the mounting tab is electrically isolated from the drain. The through-hole mounting suits point-of-load boards and chassis-mount designs. Maximum power dissipation is 30 W at case temperature, limited by the full-pack construction. For continuous high-current operation, ensure adequate heatsinking and airflow; the junction-to-case thermal path is the constraint.

Frequently asked questions

What is the replacement for STF80N10F7?

STMicroelectronics has not published a direct pin-compatible replacement for the STF80N10F7 in the available records. For a form-fit-function substitute, evaluate other 100 V N-channel MOSFETs in the TO-220FP package with similar Rds(on) and gate charge — parametric search tools can identify candidates. The STF80N10F7 itself remains available through independent channels for legacy BOM lines.

Is STF80N10F7 obsolete?

Yes, the STF80N10F7 is listed as obsolete by STMicroelectronics. It is not in current factory production. For sustainment or repair requirements, the part can be sourced through independent distribution against an RFQ.
