Product details

Temperature range and application environments

Rated for junction temperatures from -55°C to 150°C, the STF23N80K5 suits industrial environments where the power stage sees thermal cycling — motor drives, industrial power supplies, solar inverters, and battery chargers in outdoor cabinets. The full-pack package's isolated backside simplifies mounting to a grounded heatsink without an insulator, which is a practical advantage in assemblies where the heatsink is at chassis ground potential.

It is ROHS3 compliant. For a BOM freeze or long-term design, this is a current-generation part with no imminent LTB risk.

Frequently asked questions

What is the Rds(on) of STF23N80K5?

Maximum on-resistance is 280 mOhm at 8 A drain current with 10 V gate drive.

Is STF23N80K5 lead free?

Yes, the STF23N80K5 is ROHS3 compliant.

What is the difference between STF23N80K5 and STF25N80K5?

The STF25N80K5 is a higher-current variant in the same MDmesh™ K5 series, with a higher continuous drain current rating and typically a lower Rds(on). The STF23N80K5 is the 16 A / 280 mOhm option, while the STF25N80K5 targets designs needing more output current. Both share the same TO-220FP package and 800 V Vdss rating.
