SQJ140EP-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter or power tool power supply. PCB space is limited, yet it must handle peak currents of hundreds of amperes. Ordinary MOSFETs either have high conduction losses or are limited by package heat dissipation. The VBsemi SQJ140EP-VB is designed for precisely this—it integrates 40V withstand voltage, 150A current carrying capability, and an on-resistance of only 0.7mΩ into the compact LFPAK56 package, utilizing advanced SGT (Shielded Gate Trench) technology, allowing high-power-density designs without compromise.

Domain and module applications：
Motor Drive Modules – As power stage switches, the extremely low on-resistance significantly reduces heat generation, supporting high continuous current output.
High-Power DC-DC Converters – Replaces traditional rectifier components in synchronous rectification topologies, greatly improving conversion efficiency.
Power Tools / Garden Machinery – Withstands stall high-current surges, providing reliable overcurrent protection and stable power output.
Automotive Electronics / Vehicle Power Supplies – 40V withstand voltage combined with low-loss characteristics confidently handles vehicle grid transient fluctuations.
Battery Packs / Energy Storage Systems – Used as the main switch for charge/discharge paths, effectively reducing power losses and extending runtime.
Server Power Supplies / Telecom Base Station Power Supplies – High current density design aids module miniaturization, meeting stringent thermal requirements.
In a nutshell: The SQJ140EP-VB is not just an ordinary MOSFET; it is the "performance core" and "thermal management tool" for your high-power, high-density power designs.
