SQJ486EP-T1_BE3-VB Product details
Back to previous pageProduct introduction：
SQJ486EP-T1_BE3-VB is a Single N-MOSFET deeply optimized for medium-voltage, high-current power switching scenarios. Trench technology balances low conduction losses and high switching reliability, while the LFPAK56 package achieves an excellent balance between heat dissipation and mounting area. The combination of 80V withstand voltage, 90A current capability, and 6mΩ on-resistance makes it an ideal choice for medium-to-high-power applications such as servo power supplies, motor drives, and communication power supplies, especially for system designs requiring low impedance, high current density, and high reliability.

VDS=80V: Suitable for 24V/36V/48V systems, providing ample margin for voltage spikes, significantly reducing avalanche breakdown risk.
VGS=±20V: Compatible with 4.5V~12V logic levels, can be directly connected to MCU/driver, simplifying gate drive circuit design.
Vth=1.4V (typical): Can enter the fully enhanced region even with low-voltage drive, achieving 7.2mΩ on-resistance with 4.5V gate voltage, suitable for wide voltage drive scenarios.
RDS(on)=6mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces temperature rise under full load, can reduce heatsink size or copper area, improving system power density.
ID=90A: Ample continuous current margin, can handle peak load demands such as motor stall and power supply inrush current.
Package LFPAK56: Low parasitic inductance, low thermal resistance, supports high-frequency switching, while saving PCB area compared to traditional DPAK/D2PAK, beneficial for compact layout.
