Detailed parameter description
- **V_DS (drain-source voltage)**: -12V
The maximum voltage that the MOSFET can withstand between the drain and source.
- **V_GS (gate-source voltage)**: ±12V
The maximum voltage allowed between the gate and source of the MOSFET.
- **V_th (gate threshold voltage)**: -0.8V
The minimum gate-source voltage required to make the MOSFET start to turn on.
- **R_DS(ON) (drain-source on-resistance)**:
- 40mΩ @ V_GS = 2.5V
- 21mΩ @ V_GS = 4.5V
- 18mΩ @ V_GS = 10V
The resistance between the drain and source of the MOSFET in the on state. Lower R_DS(ON) values indicate higher switching efficiency and lower power losses.
- **I_D (continuous drain current)**: -6A
The maximum continuous drain current that the MOSFET can withstand.
- **Technology**: Trench
Using Trench technology, it provides low on-resistance and high current handling capability.
