Explore our leading selection of high-efficiency, medium and low voltage power components engineered for rugged home appliance applications.
HONGKONG Olukey INDUSTRY CO., LIMITED is a premier solution provider focusing on the overall integration and optimization of high-reliability electronic components. Operating at the intersection of technological innovation and manufacturing excellence, our primary product portfolio is structured across three core competencies: WINSOK MOSFETs, Cmsemicon MCUs, and bespoke PCBA circuit board solutions.
Today, Olukey Industry's advanced solutions serve as foundational building blocks for critical industries worldwide. From automotive electronics and military-grade machinery to intelligent industrial grids, new energy infrastructure, smart medical hardware, 5G networks, the Internet of Things (IoT), and smart home appliances, we build component networks that power tomorrow. Backed by global general agent agreements with major original semiconductor fabricators, we are deeply rooted in the Asia-Pacific market, servicing global supply networks with premium electronics, logistical agility, and engineering consulting services.
Understanding the strategic advantages that empower our manufacturing facility to deliver superior, cost-effective equivalents for tier-one global brands.
Based in the technology cluster of Shenzhen and Hong Kong, we leverage a robust localized network. This ecosystem guarantees stable raw wafer supply, high-precision assembly lines, and immediate raw material availability, mitigating geopolitical and transit risks.
Through massive production runs and streamlined design cycles, our factory offers a significantly optimized cost-to-performance ratio. These efficiency gains translate directly into cost savings for global OEMs searching for drop-in alternative components.
Our backend packaging facilities rely on state-of-the-art automated optical inspection (AOI), X-ray imaging, and automated testers. We assure rigorous failure analysis and electrical verification before shipping to global distributors.
Our commitment to survival is anchored in reputation, adhering strictly to the principle of "Quality First, Service First." Over the years, we have built cooperative bonds with key high-tech entities and original device manufacturers (IDMs) locally and internationally. By combining technical insight with supply chain logistics, we ensure that every client experiences seamless component matching and zero-downtime procurement.
WINSOK MOSFET's voltages span medium and low ranges: 15V, 20V, 30V, 40V, 60V, 80V, 100V, 120V, 150V, 200V, 250V, 300V, 400V, 500V, 600V, and 650V. We provide more than 600 distinct models across 40+ package configurations, including DFN3X3-8, DFN5X6-8, TO-252, TO-263, SOP-8, SOT-23, and TO-220. This extensive catalog allows us to address nearly any consumer electronics board layout requirement.
Sourcing equivalent MOSFETs requires rigorous verification. Below is a detailed view of how we map parameters to replace major industry parts.
In modern power electronic designs, procuring alternative components is no longer simply about matching package size. To maintain system reliability and prevent unexpected Field Return Unit (FRU) failures in home appliances, design engineers evaluate critical electrical specifications. Key parameters include: Drain-to-Source Breakdown Voltage (VDS), On-State Resistance (RDS(on)), Gate Charge (Qg), and Continuous Drain Current (ID).
WINSOK MOSFET equivalents are designed and tested to match or exceed top-tier international competitors like Infineon, Onsemi, STMicroelectronics, and Alpha & Omega Semiconductor (AOS). Our focus is to deliver "pin-to-pin, drop-in replacement" capabilities. By maintaining the same footprint, thermal characteristics, and gate drive parameters, engineers can integrate WINSOK parts without altering their existing PCB design or controller algorithms.

Home appliances require power switches capable of handling continuous cycling, thermal stress, and voltage spikes. WINSOK MOSFETs and Cmsemicon MCUs are optimized for several target applications:
Aligning with global standards to ensure seamless integration and long-term reliability in major consumer markets.
All component lines, including WINSOK MOSFETs and Cmsemicon MCU developments, comply with RoHS, REACH, and CE requirements. We use lead-free finishing and flame-retardant encapsulation materials to meet strict European and American safety guidelines.
Olukey Industry provides Field Application Engineering (FAE) services across major hubs. We assist customer design teams with schematics optimization, layout reviews, thermal dissipation simulations, and EMI troubleshooting.
As global regulations enforce stricter energy ratings (such as Energy Star and ErP directives), our components are designed to reduce parasitic capacitances (Ciss, Crss) and optimize RDS(on) to minimize standby power losses.
Answers to common technical, logistics, and supply questions regarding WINSOK MOSFETs and equivalent designs.
Our engineering team provides complete cross-reference matching based on your current component's datasheet. We review critical parameters like VDS, RDS(on), and Gate Charge (Qg) to ensure compatibility.
Yes, our equivalents are designed to match standard industry packages (SOP-8, DFN3X3, DFN5X6, TO-252, TO-220). In most cases, they can be placed on existing layouts without board changes.
We use automated optical inspection (AOI), static parameter testing, and dynamic switching analysis. Standard reliability tests include High Temperature Reverse Bias (HTRB) and High Temperature Gate Bias (HTGB).
All products are RoHS and REACH compliant. We also provide select components that meet automotive-grade AEC-Q101 requirements.
Standard items in high demand are typically stocked in our warehouses. For factory-direct production runs, typical lead times range from 4 to 8 weeks, depending on the package type.
Yes. We specialize in custom PCBA development, combining Cmsemicon MCUs with WINSOK MOSFETs to deliver complete motor drive and power management boards.
