SQJ488EP-T1_BE3-VB Product details
Back to previous pageProduct introduction：
SQJ488EP-T1_BE3-VB is a Single N-MOS deeply optimized for medium-to-high voltage power switching scenarios. The Trench technology balances low conduction loss with high switching speed, and the LFPAK56 package achieves a good balance between heat dissipation capability and board space. The combination of 100V withstand voltage, 69A current-carrying capacity, and 11.6mΩ on-resistance makes it an ideal replacement for traditional DPAK or D2PAK packaged devices in server power supplies, industrial control, and automotive systems, especially suitable for applications requiring high power density and high reliability.

VDS=100V: Suitable for 24V/48V/60V systems, with ample margin for voltage spikes, significantly reducing avalanche breakdown risk and improving system robustness.
VGS=±20V: Compatible with 4.5V~12V logic levels, can be directly controlled by MCU/PMIC or dedicated gate drivers, simplifying peripheral design.
Vth=1.4V (typical): Fully turns on even with low gate drive voltage, maintaining stable conduction during battery voltage drops or low drive voltage conditions.
RDS(on)=11.6mΩ @ VGS=10V: Ultra-low on-resistance, greatly reduces full-load losses, allowing smaller heatsink size and PCB copper area.
RDS(on)=13.92mΩ @ VGS=4.5V: Excellent conduction performance even under low-voltage drive, compatible with 5V logic level applications, reducing drive power consumption.
ID=69A: Ample continuous current margin to handle motor stall, surge currents, and peak demands of high-power loads, ensuring high reliability.
Package LFPAK56: Metal leadframe structure, low thermal resistance, high current density, supports high-frequency switching, saves PCB area, and improves heat dissipation efficiency.
