Instructions for Use:

  1. Thermal Management:

    • Ensure adequate heat sinking to manage the power dissipation, especially when operating near the maximum continuous drain current.
    • The thermal resistance (RθJC) from junction to case is 0.45°C/W. Use this value to calculate the required heat sink size.
  2. Gate Drive:

    • Apply a gate-source voltage (VGS) between -15V and +15V. For optimal performance, use VGS = 10V or higher to minimize RDS(on).
    • Ensure the gate drive circuit can provide sufficient current to charge and discharge the gate capacitance quickly, reducing switching losses.
  3. Overcurrent Protection:

    • Implement overcurrent protection to prevent damage from excessive drain current. The device can handle up to 117A in short pulses, but prolonged exposure to high currents can lead to overheating and failure.
  4. Storage and Handling:

    • Store the device in a dry environment within the temperature range of -55°C to 175°C.
    • Handle with care to avoid static discharge, which can damage the MOSFET.
  5. Mounting:

    • Use appropriate mounting techniques to ensure good thermal contact with the heat sink. Apply thermal paste or a thermal pad between the MOSFET and the heat sink for better heat transfer.
  6. Electrical Connections:

    • Ensure all connections are secure and free from corrosion. Use proper wire gauges to handle the expected current levels without significant voltage drops.
  7. Testing:

    • Before final assembly, test the device under controlled conditions to verify its performance and ensure it meets the specified parameters.
