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.
