FAE Expert Insights
"The IXFH50N20 is a solid choice for 200V industrial applications requiring 30-50A capability. I've successfully used this MOSFET in numerous industrial power supply designs. The 45mΩ Rds(on) provides good efficiency, and the 200V rating offers adequate margin for 48V and 110V industrial systems. The avalanche capability is particularly valuable in industrial environments where voltage transients are common. I recommend this device for applications requiring higher voltage margin than 150V devices can provide. Use proper gate drive (12-15V) and ensure adequate heatsinking for continuous operation above 30A."

Frequently Asked Questions
What applications benefit most from the 200V rating?
The 200V rating of IXFH50N20 is ideal for: (1) 48V industrial systems with high voltage transients - provides 4x voltage margin; (2) 110V DC bus applications - common in industrial equipment; (3) Battery-powered systems with 96V nominal voltage; (4) Motor drives with 90V DC bus; (5) Power supplies with 150V rectified input. The higher voltage rating provides better reliability margin compared to 150V devices in industrial environments where voltage spikes are common. For 24V and 48V systems without significant transients, lower voltage devices may offer better Rds(on) performance.
Choose for 48V+ industrial systems or applications with significant voltage transients.
How does this compare to the IXTP96N15T for 48V applications?
Comparing IXFH50N20 (200V) vs IXTP96N15T (150V) for 48V applications: (1) Voltage margin - IXFH50N20 provides 4x margin vs 3x for IXTP96N15T; (2) Current capability - IXTP96N15T handles 96A vs 50A for IXFH50N20; (3) Rds(on) - IXTP96N15T has 6.5mΩ vs 45mΩ for IXFH50N20 (much lower conduction losses); (4) Cost - IXTP96N15T typically more cost-effective per amp. For 48V applications without extreme transients, IXTP96N15T is usually the better choice due to much lower Rds(on). Choose IXFH50N20 only if you need the extra voltage margin for reliability in harsh industrial environments.
Use IXTP96N15T for most 48V applications; IXFH50N20 only if extra voltage margin is required.
