The 2SK1764 is an N-channel power MOSFET from Hitachi, Ltd., designed for high-speed switching applications. This MOSFET is characterized by its low on-resistance and fast switching speed, making it suitable for use in power supplies, motor control, and various other power electronic circuits where efficiency is paramount.

Applications

• Switching Regulators
• DC-DC Converters
• AC-DC Power Supplies
• Motor Control Circuits
• Solid State Relays

Features

• N-Channel MOSFET
• Low drain-source on-resistance (RDS(on))
• High-speed switching capability
• Avalanche energy rated
• Enhancement mode operation

Benefits

• Improved power conversion efficiency due to the low RDS(on), which minimizes conduction losses.
• Reduced switching losses and enhanced system performance due to fast switching speeds.
• Increased ruggedness and reliability due to the avalanche energy rating.

Additional Details

The 2SK1764 is typically available in a TO-220 package or similar. Key electrical parameters include Drain-Source Breakdown Voltage (VDS), Gate-Source Threshold Voltage (VGS(th)), Drain-Source On-Resistance (RDS(on)), and Total Gate Charge (Qg). It is essential to consult the datasheet for precise values to ensure proper application and safe operation. Heat sinking is often necessary to manage power dissipation effectively, especially at higher current levels. Consideration should be given to the device's switching times (turn-on delay time, rise time, turn-off delay time, and fall time) in high-frequency applications. The device's gate-source and drain-source capacitances also influence its switching characteristics.
