CSD17318Q2-VB Product details
Back to previous pageProduct introduction：
** The CSD17318Q2-VB is a Single N-MOSFET deeply optimized for low-voltage power switching applications. The Trench technology balances low switching losses with high reliability, and the DFN6(2X2) package strikes a balance between heat dissipation and footprint. The combination of 30V withstand voltage, 10A current capability, and 17mΩ on-resistance makes it an ideal cost-effective upgrade option to replace traditional SOT-23 or SOP-8 packaged devices, especially suitable for high-density, high-volume applications.**

- **VDS=30V**: Suitable for 5V/12V/24V systems, providing ample margin for voltage spikes, reducing avalanche breakdown risk.
- **VGS=±20V**: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating level-shifting circuits.
- **Vth=1.5V (Typical)**: Can still enter the fully enhanced region with low-voltage drive, especially suitable for battery voltage decay scenarios.
- **RDS(on)=17mΩ @ VGS=10V**: Ultra-low on-resistance, significantly reduces full-load temperature rise, can reduce heatsink copper area; on-resistance is 21mΩ @ VGS=4.5V, supporting low-voltage logic drive.
- **ID=10A**: Ample continuous current margin, can handle peak demands of most portable and automotive auxiliary loads.
- **Package DFN6(2X2)**: Ultra-small size, low parasitic parameters, supports high-frequency switching, while saving PCB area and assembly costs.
