DMN53D5L-13-VB Product details
Back to previous pageProduct introduction：
DMN53D5L-13-VB is a Single N-MOS optimized for small-signal low-voltage switching scenarios. Trench technology balances low losses with high reliability, while the SOT23-3 package strikes a balance between heat dissipation and board space. The combination of 60V withstand voltage, 0.3A current capacity, and 2800mΩ on-resistance makes it an ideal small-signal alternative to traditional SOT-23 or SOT-89 packaged devices, especially suited for high-density, low-power applications.

VDS=60V: Suitable for 12V/24V/48V systems, provides ample voltage spike margin, reduces avalanche breakdown risk.
VGS=±20V: Compatible with 3.3V~12V logic levels, can directly connect to MCU/PMIC, eliminating level-shifting circuits.
Vth=1.7V (typical): Fully enters conduction region even with low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=2800mΩ @ VGS=10V: Moderate on-resistance, suitable for small current signal switching, low voltage drop at full load, reducing heat generation.
ID=0.3A: Continuous current meets most logic control, drive isolation, and sampling circuit requirements, with reasonable margin.
Package SOT23-3: Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and assembly cost.
