The IRF830-H is an N-channel enhancement mode power MOSFET from Harris Corporation (now part of Renesas). This device is designed for high voltage, high-speed power switching applications.

Applications

• High-efficiency switch mode power supplies
• Uninterruptible power supplies (UPS)
• Motor control circuits
• High voltage DC-DC converters
• Lighting ballasts

Features

• N-Channel enhancement mode
• High voltage capability (typically 500V)
• Fast switching speed
• Low drain-source on-resistance (RDS(on))
• Avalanche energy rated
• Simple drive requirements

Benefits

• Improved power supply efficiency due to low RDS(on)
• Reduced switching losses due to fast switching speed
• Simplified circuit design due to simple drive requirements
• Increased system reliability due to avalanche energy rating
• Cost-effective solution for high voltage power switching

Additional Details

The IRF830-H typically features a voltage rating of 500V, a continuous drain current of around 4.5A - 5A (depending on the exact specification). It is commonly available in a TO-220 package. The low on-resistance minimizes conduction losses, contributing to higher overall efficiency. The fast switching speed also reduces switching losses, making it suitable for high-frequency applications. The device's ruggedness and avalanche energy rating provide added protection against voltage transients and overvoltage conditions.
