How Hongkong Olukey Industry Co., Limited delivers mission-critical components, technical engineering support, and reliable logistics globally.
In the rapidly evolving landscape of advanced electronics, acquiring highly reliable semiconductor products is paramount. As a top-tier solutions provider, HONGKONG Olukey INDUSTRY CO., LIMITED stands at the intersection of quality assurance, technical depth, and robust supply chain networks. By integrating advanced WINSOK MOSFETs, high-performance Cmsemicon MCUs, and bespoke PCBA circuit board solutions, we optimize components for the world’s most demanding industries.
Operating across the strategic hub of the Asia-Pacific region, we work hand-in-hand with major original fabs to secure factory-direct allocations. Our engineering-driven approach ensures that procurement managers and R&D departments bypass the common hurdles of obsolete components and extended lead times.
Our core pillars ensure that your design projects and assembly lines run without interruption, from prototype to mass production.
We adhere to strict quality control policies, verifying the traceability of all active and passive components from the original wafer down to the packaged device.
By keeping a strategic safety stock of WINSOK MOSFETs and Cmsemicon MCUs, we protect our international clients against volatile chip shortages.
We go beyond simple distribution. Our seasoned R&D engineering team designs custom PCBA board schematics, firmware integrations, and circuit optimizations.
In power semiconductor designs, sourcing drop-in replacements is a critical strategy to prevent production stops. The WINSOK MOSFET Universal Series offers precise pin-to-pin, electrical-equivalent cross-references for major brands like Infineon, Onsemi, Diodes Inc., and AOS. Contact our FAE (Field Application Engineering) desk for detailed comparison datasheets.
The WINSOK MOSFET line covers an extensive voltage spectrum, offering solutions tailored for low-power consumer wearables up to high-power industrial equipment. Featuring over 600 models across more than 40 standard packaging styles, we address complex design specifications:
Simultaneously, the Cmsemicon MCU line adds intelligence, featuring ARM Cortex-M0+ architectures and proprietary 8-bit/32-bit controllers, ideal for motor control, wireless smart home products, and industrial automation.

| TO-252 / TO-263 | 40V - 150V | 3 mΩ to 35 mΩ | Motor Drivers, Electric Vehicles (EV), Inverters, Power Supplies |
| TOLLA-8L | 60V - 150V | < 0.9 mΩ to 2 mΩ | High Current Automotive, Server Power Supply, Industrial BLDC Motors |
| SOT-23 / SOP-8 | 12V - 60V | 15 mΩ to 80 mΩ | Consumer Electronics, Handheld Devices, Power Management Units (PMU) |
China, specifically the Shenzhen-Hong Kong semiconductor cluster, represents the pinnacle of modern electronics fabrication and packaging technology. By collaborating with Shenzhen's leading fabrication facilities, we capitalize on:
Fabs utilize state-of-the-art wire bonding and advanced mold compounds, resulting in low parasitic inductance and exceptional thermal cycling capability.
2. Unparalleled Scale and Cost Efficiency:Mass-production scaling lowers processing costs without compromising wafer quality. This allows us to pass competitive pricing directly to our global customers.
3. Rapid Prototyping and Custom PCBA Iteration:Proximity to Shenzhen’s hardware ecosystems means custom revisions, pilot builds, and testing are completed in a fraction of standard lead times.
Managing cross-border supply chains requires strict adherence to international regulatory standards. At Hongkong Olukey Industry Co., Limited, we guarantee that all products comply with globally recognized environment and safety policies:
The semiconductor market is witnessing a shift towards high-frequency, highly integrated topologies. Silicon remains the cornerstone for low and medium-voltage applications, but new system designs place extreme demands on switching efficiency.
With the rise of renewable energy systems, high-density server power supplies, and electric mobility (EVs, e-bikes), designers require discrete components that occupy minimal board space while handling high surge currents. Our development roadmap actively focuses on packaging techniques like TOLLA and DFN, which minimize inductances and improve thermal resistance ($R_{thJC}$), allowing system designers to increase power density without risking thermal runaway.
Our portfolio of components is optimized to serve as the structural backbone of critical modern electronics:
Used in body control modules (BCM), electronic power steering (EPS), infotainment systems, and LED lighting arrays where thermal robustness is mandatory.
Utilizing low-voltage P-Channel MOSFETs (like WST2333A) for load switches and 32-bit MCUs (like BAT32G127) for local smart logic control.
High-power N-channel devices (e.g. WSM400N06G and WSD30140DN56) serve in protection circuits, BMS modules for Li-ion packs, and solar power inverters.
Answers to critical inquiries regarding sourcing, equivalents, quality, and supply security.
Our core mission at HONGKONG Olukey INDUSTRY CO., LIMITED is to become a high-value global agent. By adhering to the corporate values of "Pragmatism, Win-win, Service and Responsibility," we consistently improve service quality. We work closely with our component suppliers and logistics networks to explore new markets, providing design engineers with the tools to construct high-efficiency devices.
Whether your project requires custom microcontroller programming, PCB layouts, thermal management solutions, or a reliable supply of discrete components, Olukey provides the support needed to maintain product quality and avoid supply chain disruption.
