Instructions for Use:

1. Supply Voltage (V_DD):

   • 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 (I_D):

   • 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 (I_Dpeak):

   • 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 (V_GS):

   • 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 (V_GS(th)):

   • The device will start conducting when the gate-source voltage reaches approximately 1.5 V (typical).

6. On-State Resistance (R_DS(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 (P_TOT):

   • 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 (T_j):

   • The maximum junction temperature is 150°C. Ensure proper thermal management to keep the junction temperature within safe limits.

9. Storage Temperature (T_stg):

   • 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.
