Key Features
- 500V breakdown voltage with 21A drain current enabling high-power switching in offline and industrial converter topologies
- 0.158Ω maximum RDS(on) minimizing conduction losses for high-efficiency operation in switch-mode power supplies
- 430mJ avalanche energy rating providing robust protection against inductive switching transients in motor drive applications
- Integrated body diode in TO-263AB surface-mount package simplifying PCB layout and eliminating external freewheeling diode
Applications
The STB28NM50N is designed for high-voltage switch-mode power supplies, motor drive inverters, and industrial DC-DC converters where 500V blocking voltage and low RDS(on) are required simultaneously. Its built-in body diode and 430mJ avalanche rating make it well suited for hard-switched topologies such as boost converters, flyback converters, and half-bridge circuits in PFC stages. The device is also used in solar inverters, UPS systems, and industrial welding equipment requiring robust N-Channel MOSFET performance at high voltages.
