Explore our highly reliable, top-tier parameters MOSFETs engineered for UPS converters, synchronous rectification, and battery management boards.
Uninterruptible Power Supply (UPS) systems serve as the structural backbone for global computing, modern data centers, and advanced automation facilities. However, high procurement dependencies on a limited cohort of Tier-1 power semiconductor brands expose global manufacturers to persistent risks of lead-time variance and supply bottlenecks.
As modern infrastructure migrates towards microgrids and high-power-density server configurations, the requirement for robust power switching devices becomes paramount. Securing reliable ODM MOSFET alternatives isn't merely a strategy for cost mitigation—it is a critical imperative for ensuring operational continuity and product portfolio flexibility.
Our solutions target these industrial friction points by providing pin-to-pin, parameter-matched alternatives that integrate seamlessly into existing PCB topologies, ensuring zero redesign cycles and accelerating time-to-market.

Understanding how different MOSFET parameters impact power efficiency across the distinct stages of Uninterruptible Power Supply systems.
In double-conversion UPS, the Power Factor Correction stage demands rapid switching frequencies to minimize inductor size. WINSOK Super Junction N-channel MOSFETs deliver low gate charges ($Q_g$) and reduced reverse recovery losses ($Q_{rr}$), enabling high-density conversions with minimal system heat generation.
High-current, low-conduction-loss switches are critical for modern lithium-ion and lead-acid battery management subsystems. Medium-voltage (60V to 100V) MOSFETs with Ultra-Low $R_{DS(on)}$ (less than 2mΩ in standard packages) minimize thermal stress and extend cell cycle life during storage charging cycles.
The DC-AC conversion block relies on precise timing. Our optimized packaging models (DFN5x6, TO-220, and TO-263) minimize parasitic source inductance, preventing gate oscillation, reducing EMI signatures, and maximizing operational output efficiency.

| Inverter High-Frequency Switch | 60V - 150V | High Junction Temp Support ($T_j = 175^\circ C$) | TO-220 / TO-263 | WSF80N06H (60V 80A) / WSR160N20 (200V 160A) |
| DC-DC Output Sync-Rectification | 15V - 60V | Ultra-Low Gate Drive Requirements ($V_{gs(th)}$) | DFN2x2 / DFN5x6 / SOP-8L | WSD4018DN22 (-40V -18A) / WST3035 (-30V -4.4A) |
How our semiconductor production lines are engineered to meet global standards for environment-friendly and highly efficient components.
Power Usage Effectiveness (PUE) is the gold standard metric for assessing data center environmental impact. High-power-density server systems convert substantial volumes of electricity into heat. Every fraction of a percent of efficiency saved at the UPS stage translates directly to megawatt-hour savings in cooling overhead.
By leveraging WINSOK MOSFETs with structural improvements in active-area trench geometry, system designers can decrease conduction losses by up to 12%. This direct reduction in thermal dissipation means lower load requirements for air conditioning, lowering PUE and assisting clients in achieving strict carbon neutrality metrics.
All semiconductor solutions designed by HONGKONG Olukey INDUSTRY CO., LIMITED conform strictly to international safety and environment protocols. We run our lines under clean-room conditions certified to standard ISO9001 quality management benchmarks, and guarantee compliance with RoHS and REACH regulations, eliminating supply issues when entering strict regulated regions like North America and the EU.
Our collaborative China-based production facilities leverage Factory 4.0 automation architectures. Real-time statistical process control (SPC) lines monitor silicon thickness consistency down to nanometer deviations, resulting in highly stable threshold voltage ($V_{GS(th)}$) bands across separate production runs.
By using modern die-attachment processes and automated high-magnification optical inspections, we reduce micro-voiding beneath the silicon die. This ensures a uniform thermal transfer surface to the exterior copper tab of packages like the TO-220 and DFN5x6, reducing local hot spots and raising overall system durability during current surges.
While global lead times for Tier-1 power MOSFETs can spike unexpectedly, our factory's direct partnerships and robust raw material procurement buffers allow us to keep production lead times stable. With buffer stocks ready for high-demand packages like DFN5X6-8L and TO-252-2L, we help global buyers prevent manufacturing stoppages.
