VDS=40V: Suitable for 5V/12V/24V systems, providing sufficient voltage spike margin, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can directly connect to MCU/PMIC, simplifying drive circuit design.
Vth=3V (Typical): Moderate threshold voltage, balancing noise immunity and low-voltage drive compatibility; with 4.5V or higher drive, it enters the fully enhanced region stably.
RDS(on)=1.6mΩ @ VGS=10V: Ultra-low on-resistance, extremely low full-load loss, significantly reducing temperature rise and heatsink requirements.
RDS(on)=3mΩ @ VGS=4.5V: Maintains very low on-resistance even under low-voltage drive, suitable for 5V logic direct drive scenarios.
ID=120A: Ample continuous current margin, capable of withstanding high current surges, suitable for high-power loads and battery circuits.
Package TO252: Mature surface-mount package, better thermal performance than smaller packages, easy for automated production, balancing power density and reliability.
