PHT4NQ10LT,135-VB Product details
Back to previous pageProduct introduction：
PHT4NQ10LT,135-VB is a Single N-MOS deeply optimized for medium-voltage power switching scenarios. The Trench process balances low switching loss and high reliability, and the SOT223 package achieves a good balance between heat dissipation performance and board area. The combination of 100V withstand voltage, 5A current carrying capacity, and 100mΩ on-resistance makes it an ideal cost-reduction incremental option for replacing traditional DPAK or SOP-8 package devices, especially suitable for high-density, high-volume applications.

VDS=100V: Suitable for 24V/48V/60V systems, providing ample voltage spike margin to reduce avalanche breakdown risk.
VGS=±20V: Compatible with 3.3V~12V logic levels, can directly connect to MCU/PMIC, eliminating level-shifting circuits.
Vth=1.8V (typical): Fully enters conduction region even at low drive voltage, suitable for battery voltage decay and multi-cell battery power supply scenarios.
RDS(on)=100mΩ @ VGS=10V (typical), 120mΩ @ VGS=4.5V: Low on-resistance, controllable temperature rise at full load, reduces required copper area for heat dissipation.
ID=5A: Ample continuous current margin to handle peak demands of most industrial and automotive auxiliary loads.
Package SOT223: Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and assembly cost; compatible with mainstream SMT processes, better heat dissipation than SOT23.
