SiC MOSFET for 400 V bus hard-switching and resonant stages
The IMBG65R163M1HXTMA1: The 217 mOhm maximum on-resistance at 18 V gate drive and 5.7 A sets the conduction loss baseline for a 400 V DC bus PFC or LLC converter stage.
Switching loss budget — gate charge and capacitance
Total gate charge is 10 nC at 18 V. Input capacitance measures 320 pF at 400 V drain-source bias.
Package and thermal path
The large exposed drain tab requires a soldered copper plane on the PCB for effective heat spreading — a two-layer board with minimal copper will bottleneck the thermal performance.
ROHS3 compliant.
