Product details

80 V, 180 A, 2.1 mOhm — high-current switching MOSFET

The 193 nC typical gate charge at 10 V keeps switching losses manageable in hard-switched topologies up to the mid-hundred-kHz range.

Conduction loss and thermal budget

At 2.1 mOhm Rds(on) the conduction loss at 90 A is under 17 W — the 315 W power dissipation rating at Tc=25°C gives substantial headroom, but the real thermal limit is set by the junction-to-case thermal resistance and the heatsink. Input capacitance Ciss is 13600 pF at 50 V Vds — the gate driver must source 193 nC per switching cycle. At 100 kHz the average gate drive current is 19.3 mA; a driver rated for 2 A peak handles the capacitive load without excessive rise time.

Package and mounting

Supplied in the H²PAK package (TO-263-7, 6 leads plus tab), a surface-mount D²Pak variant with a large copper tab for solder-down heatsinking. Surface mount assembly with standard reflow profiles;.

Lifecycle and supply posture

ROHS3 compliant.

Frequently asked questions

What is the Rds(on) of the STH270N8F7-6?

The maximum Rds(on) is 2.1 mOhm at 90 A drain current with 10 V gate drive. This is the on-resistance at 25°C junction temperature; expect it to increase by roughly 50% at 125°C junction per the typical MOSFET temperature coefficient.

Is the STH270N8F7-6 lead-free?

Yes, it is ROHS3 compliant, meaning it meets the European RoHS directive for lead and other restricted substances.

What package does the STH270N8F7-6 come in?

It is supplied in the H²PAK package, which is a TO-263-7 variant with 6 leads plus a drain tab.
