Product details

Gate charge and switching — what the 193 nC Qg means for the driver

The STH275N8F7-2AG: A gate charge of 193 nC at 10 V is moderate for a die this size — it means the gate driver needs to source and sink that charge quickly to achieve fast switching. Pair this MOSFET with a driver rated for at least 2 A peak output current to keep turn-on and turn-off edges clean. PCB layout should minimise the gate-loop inductance between driver output and the H2Pak-2 gate pin.

Thermal budget — 315 W dissipation, but only with proper heatsinking

The H2Pak-2 (TO-263) package's exposed tab must be soldered to a large copper plane on the PCB or bolted to a metal chassis for thermal transfer.

It is RoHS3 compliant and available through independent distribution.

Frequently asked questions

What is the closest pin-compatible alternative to STH275N8F7-2AG?

Within the same STripFET F7 family, the STH275N8F7-2 (without the -AG suffix) is pin-compatible but lacks AEC-Q101 qualification. For automotive designs requiring the -AG's qualification, no direct second source is listed; the -2AG is the AEC-Q101 variant.

Is STH275N8F7-2AG RoHS compliant?

Yes, it is ROHS3 Compliant per the lifecycle record.

Can STH275N8F7-2AG replace STH275N8F7-2 in a design?

Yes, if the design requires AEC-Q101 qualification — the -2AG adds that qualification while maintaining the same 80 V, 180 A, 2.1 mOhm ratings and H2Pak-2 package. The -2 is the non-automotive variant; swapping to the -2AG adds automotive-grade reliability without changing the footprint or electrical performance.
