Key Selection Criteria
VDS=-30V: Suitable for negative voltage switching or power rail control in 5V/12V/24V systems, providing sufficient voltage margin for spikes and reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can directly interface with MCU/PMIC, eliminating level-shifting circuits.
Vth=-1.7V (Typical): Fully turns on even with low gate drive, ideal for battery voltage decay scenarios.
RDS(on)=49mΩ @ VGS=10V: Low on-resistance ensures controlled temperature rise under full load, reducing required copper area for heat dissipation.
ID=-4.8A: Ample continuous current margin to handle peak demands of most portable and automotive auxiliary loads.
Package SOT23-6: Small footprint, low parasitic parameters, supports high-frequency switching, saving PCB area and assembly cost.
