60 V, 12 A N-channel — where the 9.4 mOhm Rds(on) earns its keep
The Infineon IRF7855TRPBF is a 60 V, 12 A N-channel HEXFET MOSFET in an 8-SOIC package.
Gate charge and switching — 39 nC sets the drive budget
A total gate charge of 39 nC at 10 V means a 1 A gate driver can switch this FET in about 39 ns, ignoring external gate resistance.
The 4.9 V maximum gate threshold at 100 µA drain current gives a comfortable noise margin for 10 V gate drives.
Package and footprint — 8-SOIC with standard land pattern
The supplier device package is 8-SO. Surface-mount assembly with a 2.5 W power dissipation at 25°C ambient requires a copper area on the PCB under the package to spread heat; the datasheet's thermal resistance curves assume a 1-inch-square pad.
