Product details

60 V, 70 A N-channel with 3.5 mOhm Rds(on) — TO-220FP isolation

This simplifies assembly but limits the maximum power dissipation to 33 W at case temperature — the full-pack epoxy body conducts heat less efficiently than a standard TO-220 metal tab.

Total gate charge is 55 nC at 10 V gate-source — the drive voltage required to achieve the rated 3.5 mOhm Rds(on). Input capacitance Ciss is 3100 pF typical at 25 V drain-source, which combined with the gate charge sets the switching loss at a given frequency.

It is ROHS3 compliant (lead-free, no exemptions). The base product number is STF140, and the series is STripFET™, which includes several Rds(on) and voltage variants in the same TO-220FP footprint.

Frequently asked questions

What is the Rds(on) for STF140N6F7?

The maximum Rds(on) is 3.5 mOhm at a drain current of 35 A with a 10 V gate-source drive. This is the conduction-loss specification for the part; the actual on-resistance will increase with junction temperature per the normalised curve in the datasheet.

Is STF140N6F7 RoHS compliant?

Yes, the STF140N6F7 is ROHS3 compliant — lead-free with no RoHS exemptions.

What package does STF140N6F7 come in?

The STF140N6F7 is supplied in a TO-220-3 Full Pack (TO-220FP) through-hole package. The supplier device package code is TO-220FP. It ships in Tube packaging.
