PSMN018-80YS,115-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density industrial power supply or automotive-grade DC-DC converter that needs to handle 80V high voltage and 90A high current in a limited space while minimizing conduction losses. Ordinary MOSFETs either lack sufficient voltage tolerance or have high on-resistance, leading to bulky cooling systems. VBsemi PSMN018-80YS,115-VB is designed for this purpose—it integrates 80V voltage tolerance, 90A current capability, and an on-resistance as low as 6mΩ in an LFPAK56 (compatible with PDFN 5x6) package using Trench technology, allowing high-power designs to achieve an ideal balance between efficiency and size.

Domain and module applications：
- Power Tools / Garden Machinery – As the power switch for brushless motor drive stages, low on-resistance reduces heat generation, supporting prolonged heavy-load operation.
- 48V Mild Hybrid Systems / Automotive DC-DC – Withstands 80V bus transient spikes, providing efficient and stable power conversion for automotive electronics.
- Base Station Power Supplies / Server Power Supplies – Replaces diodes in synchronous rectification or OR-ing circuits, reducing voltage drop and losses, improving overall system efficiency.
- Solar MPPT Controllers – Withstands wide voltage fluctuations from photovoltaic panels and continuous high current, ensuring stable and efficient maximum power point tracking.
- Lithium Battery Protection Boards / Energy Storage BMS – Quickly disconnects the circuit during overcurrent or short circuit, reducing energy waste during charge/discharge due to low internal resistance.
- Industrial Motor Drives / Variable Frequency Drives – High surge capability and low loss characteristics, suitable for frequent start-stop and overload conditions. **One-sentence summary:** PSMN018-80YS,115-VB is not an ordinary MOSFET; it is the "efficiency engine" and "heat dissipation terminator" for your 80V high-power designs.
