30 V N-channel for low-voltage power switching
The Infineon IRFHS8342TRPBF is a 30 V N-channel HEXFET® MOSFET in a PG-TSDSON-6 package, rated for continuous drain current of 8.8 A at 25 °C ambient (Ta) and 19 A at case temperature (Tc). The 16 mOhm max Rds(on) at 10 V gate drive sets the conduction loss floor for a 24 V or lower rail — at 8.5 A the dissipation is under 1.2 W, well within the 2.1 W package limit at ambient.
Rds(on) and gate drive — sizing the driver
Rds(on) is specified at 16 mOhm max with Vgs = 10 V and Id = 8.5 A. Total gate charge is 8.7 nC at 10 V.
PG-TSDSON-6 — rework and footprint
The 6-lead PowerVDFN (PG-TSDSON-6) has an exposed paddle on the bottom. The paddle is the main thermal path — the datasheet recommends a copper pad on the PCB with thermal vias to the inner ground plane. Reflow profile follows standard lead-free.
