High-performance medium and low voltage power switch components engineered for brushless motor drivers and high-frequency switching controllers.
Unlocking Maximum Efficiency, Low On-Resistance, and High Power Density for Next-Generation Brushless DC Systems.
Modern power electronics require uncompromising performance, especially when driving Brushless DC (BLDC) motors. BLDC motors rely on active electronic commutation, which places intense switching stress on the power stage. To achieve high efficiency and prevent thermal runaway, design engineers must select MOSFETs that are specifically optimized for motor control applications.
Unlike resistive loads, motor coils present highly inductive loads. This requires MOSFETs with rapid switching speeds, extremely low Gate Charge ($Q_g$ and $Q_{gd}$), and high-frequency body diode recovery metrics ($Q_{rr}$). In addition, low Drain-to-Source On-State Resistance ($R_{DS(on)}$) is crucial to minimize conduction losses, which directly impact energy efficiency and heatsink design.
As a global provider of electronic component solutions, HONGKONG Olukey INDUSTRY CO., LIMITED supplies high-performance WINSOK MOSFETs. We partner with engineers to deliver custom ODM and OEM semiconductor solutions that address the specific needs of electric vehicles, smart homes, and industrial robots.
Minimizes conduction heating ($I^2R$ losses) under high-current operation, ensuring components run cooler and operate reliably without oversized heatsinks.
Reduces gate drive losses and enables faster turn-on/turn-off times. This allows for high-frequency PWM switching while keeping EMI emissions to a minimum.
Provides high avalanche energy protection ($E_{AS}$) to withstand back-EMF spikes from inductive motor coils, preventing over-voltage failures.
From 15V sub-logic gates to 650V industrial-grade silicon power devices, packaged for performance.

This extensive selection allows engineering teams to identify drop-in replacements or optimize custom designs to meet performance and space requirements.
Our solutions support automotive electronics, medical hardware, industrial automation, 5G infrastructure, and smart IoT appliances. Through partnerships with regional distributors, we deliver complete component packages, including Cmsemicon MCUs and specialized PCBA designs, reducing development time for complex electronics.
Securing global electronics production through integrated logistics, reliable capacity, and cost efficiency.
Sourcing electronic components requires reliable supply lines, stable pricing, and scalable production. Purchasing from a Chinese MOSFET manufacturer provides strategic advantages for modern businesses:
Meeting stringent quality and reliability criteria for tier-1 industrial and automotive system integrators.
International procurement managers look for partners who can meet precise design specifications and guarantee long-term product availability. Key considerations when selecting an ODM/OEM partner include:
Procurement requires comprehensive batch records and long-term design support to ensure replacement components remain available for decades-long lifecycles.
Providing direct equivalents for mainstream brands (Infineon, ON Semi, STMicroelectronics, TI) simplifies second-sourcing and reduces production risks.
We support custom package requirements (such as DFN or TO variations) to fit compact spatial constraints and optimize thermal dissipation routes.
Upholding strict international certifications to ensure reliability in critical industrial and consumer markets.
To support global supply chains, our products must meet strict regulatory and quality requirements. At Olukey Industry, we provide localized support networks alongside certifications to keep production lines running smoothly.
Every Winsok MOSFET batch undergoes strict reliability testing. Our facilities and products comply with major industry standards to ensure global usability:
How high-frequency, low-resistance silicon is enabling new designs in smart mobility and automation.
The motor control industry is shifting toward higher power density and integration. As applications like robotic actuators and electric mobility grow, components must handle more power in smaller spaces.
P-channel and N-channel MOSFET configurations provide reliable power delivery for e-bikes, electric scooters, and golf carts, optimizing battery range and thermal efficiency.
Enables quiet, efficient operation in smart fans, air conditioners, vacuum cleaners, and kitchen appliances, helping designs meet strict energy efficiency standards.
Our compact DFN packages support multi-axis arm controllers, conveyor systems, and automated guided vehicles (AGVs), providing high power density in space-limited designs.
Technical answers to key design and procurement questions regarding BLDC MOSFETs.
conduction loss ($P_{cond} = I_D^2 \times R_{DS(on)}$) accounts for a large portion of the thermal load in motor control stages. Choosing a low $R_{DS(on)}$ MOSFET reduces self-heating, improves system efficiency, and allows engineers to design smaller PCBs with reduced cooling requirements.
Modern motor controllers are moving from leaded packages like TO-220 to surface-mount options like DFN5X6-8, DFN3X3-8, and TO-263. DFN packages offer lower parasitic inductance and resistance, along with an exposed pad that improves thermal dissipation directly into the PCB ground planes.
Yes. Winsok provides direct cross-references for many industry-standard MOSFETs from brands such as Infineon, ON Semi, STMicroelectronics, and TI. This helps procurement teams diversify their supply chains and mitigate sourcing risks without requiring major design alterations.
We offer full-cycle support, including electrical parameter optimization, custom chip packaging, and complete PCBA circuit board layout design. We also assist with microcontroller integration, using Cmsemicon MCUs to build complete motor control solutions.
