FAE Expert Insights
"The IXFH24N100 is an excellent choice for high-voltage applications requiring 1000V capability. I've used this MOSFET in PFC circuits and offline power supplies with excellent results. The 1000V rating provides adequate margin for universal input (85-265VAC) applications with PFC. While the Rds(on) of 385mΩ seems high compared to lower voltage devices, it's very competitive for 1000V rating. The avalanche capability is particularly important in high-voltage applications where energy stored in inductances is significant. For PFC applications, this device can handle 500-600W with proper heatsinking. I recommend using 15V gate drive and proper snubbers to minimize switching losses."

Frequently Asked Questions
What applications require 1000V MOSFETs?
1000V MOSFETs like IXFH24N100 are required for: (1) Universal input offline power supplies (85-265VAC) with active PFC - PFC output is typically 380-400VDC, requiring 1000V devices for switching; (2) Three-phase 480VAC input systems - rectified voltage is 680VDC; (3) Solar inverters with high DC link voltages; (4) High-voltage DC-DC converters; (5) Industrial motor drives with 600V+ DC bus. The 1000V rating provides necessary margin for voltage spikes and transients in these high-voltage applications. For lower voltage systems (single-phase 230VAC or 48V DC), lower voltage MOSFETs with better Rds(on) are more appropriate.
Use for universal input PFC, three-phase systems, and high-voltage DC applications.
How do I minimize switching losses in high-voltage applications?
To minimize switching losses with IXFH24N100 in high-voltage applications: (1) Gate drive - use strong gate driver (2A+) with optimized gate resistor (10-22Ω); (2) Snubbers - use RC snubbers to reduce voltage overshoot and dV/dt; (3) Layout - minimize loop inductance to reduce ringing; (4) Soft switching - use resonant or quasi-resonant topologies if possible; (5) Switching frequency - operate at moderate frequencies (50-100kHz) to balance losses with magnetics size. At 400V bus voltage, switching losses can be significant - proper snubber design is critical. The relatively low gate charge (63nC) helps minimize gate drive losses.
Use strong gate drive, proper snubbers, and consider soft-switching topologies for high-voltage applications.
