PSMN1R4-40YLD-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power-density DC-DC converter or power tool power supply, where the PCB needs to withstand hundreds of amps of current impact while controlling temperature rise and losses? Ordinary MOSFETs either have high on-resistance or limited package heat dissipation. The VBsemi PSMN1R4-40YLD-VB is designed for this exact challenge—it perfectly integrates 40V withstand voltage, 150A current capability, and an ultra-low on-resistance of only 0.7mΩ into the reinforced thermal structure of the LFPAK56 package, allowing high-current power supply designs to no longer compromise on heat or space.

Domain and module applications：
Motor Drive Modules – Acts as a power switch, handling startup and stall high currents, effectively reducing MOSFET self-heating and improving system reliability.
Power Tools / Garden Tools – Utilizes ultra-low on-resistance and the excellent heat dissipation of the LFPAK56 package to support high-load continuous output, extending tool life.
Automotive DC-DC Converters – In synchronous rectification or low-side switching applications, significantly improves conversion efficiency and reduces heatsink volume.
Lithium Battery Protection Boards – Serves as the main discharge switch in large-capacity battery packs; milliohm-level internal resistance reduces energy loss and supports high-rate discharge.
Server Power Supplies / Telecom Power Supplies – Used in ORing circuits or load switches, its 150A current capability can handle single-channel high-power output requirements.
Uninterruptible Power Supplies (UPS) – Implements low-loss, high-reliability power path control in inverter and bypass switching circuits.
High-Power Fast Charging Adapters – Replaces Schottky diodes in synchronous rectification topologies, reducing rectification losses and improving charging efficiency.
One-sentence summary: The PSMN1R4-40YLD-VB is not an ordinary MOSFET; it is your 'low-loss sword' and 'thermal weapon' for high-current, high-power-density power supply designs.
