Explore our core product lineup featuring WINSOK MOSFETs, Cmsemicon MCU integrations, and advanced PCBA solution designs optimized for industrial and automotive electronics.
Advanced Driver Assistance Systems (ADAS)—including autonomous emergency braking (AEB), lane-keep assist (LKA), adaptive cruise control (ACC), and high-resolution camera sensing—demand absolute reliability under extremely harsh electrical and environmental conditions. Power MOSFETs serve as the crucial backbone of these automotive architectures, executing high-speed power distribution and signal modulation across varying voltage rails.
For global Tier-1 automotive suppliers, ensuring zero-defect component pipelines has led to a major strategic pivot: sourcing high-performance equivalents from reliable Chinese semiconductor leaders. Factors such as AEC-Q101 certification compliance, low drain-to-source on-resistance ($R_{DS(on)}$), minimized gate charges ($Q_g$), and superior thermal resistance are mandatory when substituting legacy components like Infineon, Onsemi, or Nexperia with WINSOK MOSFETs.
Our focus at Olukey Industry is to deliver these optimized, drop-in replacement solutions that preserve original performance dynamics while optimizing procurement costs and scaling delivery security.
HONGKONG Olukey INDUSTRY CO., LIMITED is a premier global solution provider focusing on the overall distribution, engineering, and supply-chain solutioning of electronic product components.

Our engineering services are optimized to help you execute risk-free transitions. Through careful analysis of gate charge parameters ($Q_g$, $Q_{gs}$, $Q_{gd}$) and transient thermal impedance ($Z_{thJC}$), we match the switching behavior of legacy components perfectly to prevent circuit oscillation or electromagnetic interference (EMI) issues in sensitive ADAS processing units.
A closer look at how WINSOK MOSFETs and Cmsemicon MCUs operate together across specific critical subsystems inside modern smart vehicles.
Mounted on windshields and side mirrors, automotive cameras demand extremely small power supply footprints and minimal thermal emission. Utilizing our DFN3X3-8 (WSD30L68DN33) package minimizes PCB space while driving down the overall temperature profiles of camera modules, ensuring clarity even under direct sunlight.
LiDAR setups rely on quick pulsing current loops to drive laser diodes. WINSOK’s low parasitic inductance MOSFETs in DFN5x6-8 configuration enable rise times in the nanosecond range, boosting spatial detection accuracy and resolution.
Central computer units merge inputs from sensors. High-efficiency voltage converter rails use low $R_{DS(on)}$ N-channel MOSFETs (e.g., WSD30140DN56) to regulate core power grids, preventing system crashes caused by voltage drops.
We use comprehensive high-quality services to provide customers with various types of advanced high-tech electronic components, assist manufacturers in producing high-quality products and provide comprehensive services. Over the years, the company has relied on reputation to survive, adhering to the tenet of "quality first, service first", and has established good cooperative relationships with many high-tech enterprises and original manufacturers at home and abroad.
Through active market development and effective resource integration, Olukey Industry has become one of the outstanding and fast-growing agents in the Asia-Pacific region. We provide reliable global access to raw silicon, verified wafers, and state-of-the-art package formats designed to excel under pressure.

Detailed technical answers to common questions asked by hardware design engineers, sourcing managers, and Tier-1 automotive purchasers.
Yes. Most WINSOK models share identical standard footprints (e.g., DFN5*6-8, DFN3x3-8, TO-263, TO-252) and match or exceed the electrical specifications ($V_{DS}$, $I_D$, $R_{DS(on)}$, $Q_g$) of major international brands. Our engineering team provides detailed cross-reference datasheets to verify matching terminal configurations before design-in.
We partner with audited test facilities that evaluate batches through high-temperature tests, thermal shock cycles, and ESD trials. Our components are designed to withstand the harsh environments of automotive engine compartments and passenger cabins.
Crucial parameters include gate threshold voltage ($V_{GS(th)}$), output capacitance ($C_{oss}$), and package thickness. For camera modules, minimizing EMI is critical, which requires switching rise and fall times to remain stable under varying thermal conditions.
Cmsemicon MCUs supply the control logic and PWM signals, which drive the gates of WINSOK MOSFETs. This unified architecture is widely applied in smart power windows, automotive pumps, fans, and sub-power distribution networks.
Standard packages and components are kept in stock for immediate shipment. For custom OEM/ODM packaging or large volume production, typical lead times range from 4 to 8 weeks, which is significantly shorter than the lead times of traditional Western component manufacturers.
Yes, we offer free evaluation samples for qualified automotive, industrial, and consumer device projects. You can request samples directly from our product list pages or by contacting our customer service department.
Our quality assurance system tracks each part from silicon wafer processing to final package testing. By employing advanced AOI (Automated Optical Inspection) and X-ray diagnostics, we ensure that the solder joints and internal wire bonds of our DFN, TO, and SOP packages meet the high-reliability requirements of automotive installations.
With cleanroom production facilities, automated handling systems, and detailed production logs, we provide the traceability required for modern automotive electronic manufacturing services (EMS).
Minimizing power dissipation in automotive modules requires optimizing thermal pathways. Using copper clip bonding in our package lines lowers electrical path resistance, improving heat transfer directly to the PCB ground layers. This thermal efficiency helps prevent hot spots inside closed modules, such as rearview camera enclosures and ultrasonic sensor units.
Whether you need custom P-channel options (like our WSD30L30DN33 or WSD30L68DN33) or high-density N-channel packages (such as WSD30140DN56), Olukey Industry delivers reliable power management solutions for demanding applications.
