HONGKONG Olukey INDUSTRY CO., LIMITED stands at the forefront of power semiconductor distribution and integration. We specialize in delivering a comprehensive, three-pronged system solution encompassing high-performance WINSOK MOSFETs, advanced Cmsemicon MCUs, and turnkey PCBA circuit board design and development.
By bridging the gap between top-tier chip manufacturers and global commercial enterprises, we support micro-applications and macro-industrial systems alike. Our footprint covers critical industrial fields, including automotive systems, military-grade electronics, smart energy networks, medical appliances, and modern IoT smart homes.
Our core mission revolves around "Quality First, Service First". We work in tandem with original manufacturers in the Asia-Pacific region to design out supply-chain fragility. By securing direct access to original production channels, Olukey provides premium components that eliminate typical OEM sourcing vulnerabilities.
The WINSOK MOSFET range spans from low-voltage DC-DC converters to high-voltage offline switches, packed in compact footprints such as DFN3X3-8, DFN5X6-8, TO-252, TO-263, SOP-8, SOT-23, and TO-220. This allows appliance brands to transition smoothly from legacy packages to modern, space-efficient designs without sacrificing thermal dissipation capability.
Modern purchasing managers require strict supply chain contingency planning. Olukey offers comprehensive cross-reference matching for WINSOK MOSFETs against major Western and Japanese brands. Our components serve as direct drop-in alternatives, safeguarding production timelines against unexpected component shortages.
Regulatory bodies worldwide continue to tighten efficiency mandates (e.g., ErP Lot 6, Energy Star). Achieving lower standby power and high operational efficiency demands power MOSFETs with minimal On-Resistance ($R_{DS(on)}$) and exceptionally low Gate Charge ($Q_g$). WINSOK technology ensures optimized switching speeds and minimized thermal losses.
Home appliances face fluctuating electrical environments and constant heat cycling. Whether in motor control drives or power supply stages, our parts feature high avalanche ruggedness (UIS) and low junction-to-case thermal resistance ($R_{thJC}$), preventing early stage component degradation and costly field returns.
Providing high-efficiency component frameworks to drive next-generation home appliance design and industrial application development.
Utilized in high-end washing machines, refrigerator compressors, and air conditioner blowers. Our 40V-100V N-channel and P-channel MOSFETs (such as the DFN5X6-8 series) ensure smooth vector control (FOC) and silent motor operation.
Supports robust AC-DC converter topologies in smart microwave ovens, induction cookers, and coffee machines. Excellent low $R_{DS(on)}$ parameters minimize conduction losses during heavy loading cycles.
Perfect for cordless vacuum cleaners, robotic sweepers, and portable kitchen appliances. Provides safe, reliable charge and discharge protection using high-current, low-profile DFN package variants.
Pairs seamlessly with Cmsemicon MCUs for automated home nodes. Small footprint SOT-23 and SOP-8 dual MOSFET configurations enable ultra-compact PCB layouts and efficient thermal control in confined housings.
As home appliances evolve towards IoT integration and artificial intelligence, the demands on power distribution networks increase exponentially. Olukey is continuously aligning with new material technologies to support this transition.
Our future roadmap focuses on accelerating the deployment of wide-bandgap (WBG) options, refining sub-micron silicon structures, and developing multi-chip modules (MCM) that integrate gate drivers with active switching elements. By packing more power capability into smaller packages, we help designers squeeze maximum efficiency out of space-constrained power boards.
Industrial and domestic appliances must comply with safety standards such as UL, IEC, CE, RoHS, and REACH. OLUKEY Industrial ensures all represented WINSOK MOSFETs undergo rigorous quality screening to guarantee compliance with hazardous substance regulations.
We supply safety-certified documentation, detailed device parameters, and full traceability. Leveraging warehouses in key regional logistics hubs, we provide customized buffer stock options, local field application engineering (FAE) support, and fast prototype sampling to keep your production runs running on schedule.
WINSOK MOSFETs are engineered to match or exceed the performance parameters (such as Rds(on), Gate Charge, and thermal characteristics) of leading Western brands. They offer direct pin-to-pin drop-in replacements, providing excellent reliability at a competitive price point to optimize your Bill of Materials (BOM) cost.
We provide a wide voltage spectrum from 15V up to 650V. For low-voltage DC-DC and battery-powered logic boards, 15V-60V options are ideal. For major home appliances like AC inverter motor drives, switch-mode power supplies, and induction heaters, our 100V-650V MOSFETs deliver the necessary voltage margin and safety overhead.
Yes. As a comprehensive solution provider, HONGKONG Olukey INDUSTRY CO., LIMITED offers custom PCBA development alongside component supply. We integrate WINSOK MOSFETs and Cmsemicon MCUs into optimized boards designed for motor controls, smart power modules, and IoT appliances.
We work directly with original manufacturing facilities under strict ISO-certified management protocols. Every shipment is fully traceable back to the production batch, accompanied by comprehensive electrical test logs and RoHS/REACH verification records to ensure reliable integration.
