FDH27N50
27A, 500V, Ohm, N-Channel SMPS Power MOSFET

Switch Mode Power Supplies SMPS , such as
• PFC Boost
• Two-Switch Forward Converter
• Single Switch Forward Converter
• Flyback Converter
• Buck Converter
• High Speed Switching
• Low Gate Charge Qg results in Simple Drive Requirement
• Improved Gate, Avalanche and High Reapplied dv/dt Ruggedness
• Reduced rDS ON
• Reduced Miller Capacitance and Low Input Capacitance
• Improved Switching Speed with Low EMI
• 175°C Rated Junction Temperature
