SSM3J304T(TE85L,F)-VB Product details
Back to previous pageProduct introduction：
SSM3J304T is a Single P-MOS deeply optimized for low-voltage power switching scenarios. The Trench technology balances low switching losses and high reliability, while the SOT23-3 package balances heat dissipation and board space. The combination of -20V withstand voltage, -3.5A current carrying capacity, and 71mΩ on-resistance makes it an ideal cost-reducing incremental option to replace traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, high-volume applications.

VDS=-20V: Suitable for 5V/12V systems, providing margin for negative voltage spikes, reducing avalanche breakdown risk.
VGS=±12V: Compatible with 1.8V~12V logic levels, can directly connect to MCU/PMIC, eliminating level-shifting circuits.
Vth=-0.8V (Typical): Can enter full conduction region even under low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=71mΩ @ VGS=10V: Low on-resistance, effectively reduces full-load temperature rise, can reduce heat sink copper area.
RDS(on)=90mΩ @ VGS=4.5V: Maintains good conduction characteristics under low logic levels, suitable for low-voltage drive in portable devices.
ID=-3.5A: Sufficient continuous current margin, can handle peak demands of most portable and automotive auxiliary loads.
Package SOT23-3: Small size, low parasitic parameters, supports high-frequency switching, while saving PCB area and assembly cost.
