Instructions for Use:

  1. Supply Voltage (VDD):

    • Ensure the supply voltage is within the range of 4.5 V to 5.5 V to avoid damage to the device.
  2. Continuous Drain Current (ID):

    • The continuous drain current should not exceed 2.0 A at a junction temperature of 25°C. For higher temperatures, derate the current accordingly.
  3. Peak Drain Current (IDpeak):

    • The peak drain current can reach up to 3.0 A for short durations (10 ms) at a junction temperature of 25°C.
  4. Gate-Source Voltage (VGS):

    • The gate-source voltage should be kept between -10 V and 10 V to prevent damage to the gate oxide.
  5. Gate-Source Threshold Voltage (VGS(th)):

    • The device will start conducting when the gate-source voltage reaches approximately 1.5 V (typical).
  6. On-State Resistance (RDS(on)):

    • The on-state resistance is typically 0.045 Ω at a gate-source voltage of 4.5 V and a junction temperature of 25°C. This value increases with temperature.
  7. Total Power Dissipation (PTOT):

    • The total power dissipation should not exceed 1.2 W at an ambient temperature of 25°C. Higher temperatures require additional heat sinking or cooling.
  8. Junction Temperature (Tj):

    • The maximum junction temperature is 150°C. Ensure proper thermal management to keep the junction temperature within safe limits.
  9. Storage Temperature (Tstg):

    • Store the device in an environment where the temperature ranges from -40°C to 150°C to avoid damage.
  10. Handling:

    • Handle the device with care to avoid static discharge, which can damage the gate oxide. Use appropriate ESD protection measures.
  11. Mounting:

    • Ensure good thermal contact with the PCB or heatsink to manage heat dissipation effectively. Follow recommended soldering profiles and guidelines for optimal performance.
