The FQD25N06 is an N-channel enhancement mode power MOSFET produced using Fairchild Semiconductor's advanced PowerTrench® process. This technology has been specifically tailored to minimize on-state resistance while maintaining superior switching performance and rugged avalanche characteristics. It is suitable for high efficiency synchronous rectification and DC-DC converters.

Applications:

• Synchronous rectification in switch mode power supplies (SMPS)
• DC-DC converters
• Uninterruptible power supplies (UPS)
• Motor control
• Load switching

Features:

• RDS(on) = 0.045Ω (typical) at VGS = 10V, ID = 12.5A
• Low gate charge (Qg = 16nC typical)
• Low Crss (reverse transfer capacitance)
• 100% avalanche tested
• Maximum drain-source voltage VDS = 60V
• Continuous drain current ID = 25A

Benefits:

• Increased efficiency in power conversion circuits due to low on-state resistance, reducing power losses and heat dissipation.
• Faster switching speeds result from the low gate charge and reverse transfer capacitance.
• Improved reliability due to the avalanche rating, allowing it to withstand voltage spikes.
• Simplified thermal management owing to the low RDS(on).
• Reduced component count and board space achieved through its efficient performance.

Additional Details:

The FQD25N06 is available in a TO-252 (DPAK) package for surface mounting. It is designed for applications requiring high power density and efficiency. The gate-source voltage (VGS) is rated at ±20V. The device is RoHS compliant. Careful layout is required to minimize parasitic inductance and optimize switching performance. Proper gate drive circuitry is essential to achieve optimal efficiency and prevent ringing.
