• Isolated DC-DC Converters
• Flyback Converters
• Lighting Ballasts

Features

• Low On-Resistance (RDS(on)): Minimizes conduction losses.
• Fast Switching Speed: Reduces switching losses.
• High Avalanche Ruggedness: Provides robustness against voltage transients.
• Improved dv/dt Capability: Enhanced immunity to voltage spikes.

Benefits

• Increased Efficiency: Lower conduction and switching losses lead to higher overall efficiency.
• Improved Reliability: Robust design ensures reliable operation in demanding applications.
• Simplified Thermal Management: Lower losses result in reduced heat dissipation.

Specifications

The FDPF5N50ZF typically features a drain-source voltage (VDS) of 500V, a continuous drain current (ID) of approximately 5A, and a low on-resistance (RDS(on)) of around 1.7 Ohms at VGS = 10V. It is typically available in a TO-220F package. Always consult the datasheet for the most accurate and up-to-date specifications. The gate threshold voltage is designed for optimal gate drive. The SuperFET technology offers a balance between on-resistance and gate charge for efficient switching performance. These devices require careful layout considerations for minimizing parasitic inductances and maximizing switching speed.
