Engineered to operate seamlessly across high-frequency motor controllers, offering low RDS(ON) and supreme thermal performance.
HONGKONG Olukey INDUSTRY CO., LIMITED is a premier global solution provider focusing on the overall integration of high-reliability electronic product components. Serving as a critical bridge between original design manufacturers and global enterprises, we focus heavily on the deployment of advanced semiconductor systems. Our core product lineup consists of three specialized product lines: WINSOK MOSFETs, Cmsemicon MCUs, and comprehensive PCBA circuit board solution development.
At present, the advanced component solutions of Olukey Industry are widely integrated into safety-critical and performance-demanding applications, including automotive electronics, military electronics, smart industrial networks, new energy infrastructure, smart medical devices, 5G networks, IoT ecosystems, smart home products, and high-tier consumer electronics.
Relying on the robust structural advantages of global general agents of major original factories, we are deeply rooted in the Asia-Pacific market. By providing various advanced high-tech electronic components, we enable global manufacturing corporations to achieve optimal cost-to-performance ratios and build resilient, cutting-edge products.
A synthesis of high-end quality protocols, reliable global supply chains, and extensive technical application support.
We strictly enforce a quality-first survival doctrine. Our partnerships are restricted to ISO-certified manufacturing facilities and globally recognized original manufacturers. Every semiconductor lot undergoes structural testing to secure consistent reliability.
Unlike typical distributors, Olukey provides total solution blueprints. From pairing WINSOK MOSFETs with Cmsemicon MCUs to custom PCBA board design, we offer complete electronic building blocks for robotics projects.
Leveraging our reputation, we have established long-term cooperative partnerships with tier-1 technology enterprises and local OEMs, ensuring stable supply margins even during tight global semiconductor allocation periods.
Robotic systems place high demands on power semiconductor technologies. Whether in collaborative robot (Cobot) joints, automated guided vehicles (AGVs), or high-speed manufacturing robotic arms, power components must handle severe dynamic current surges, high switching frequencies, and compact thermal configurations. The optimization of the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is critical in achieving system efficiency, safety, and positioning accuracy.
Motor drivers in robotics typically employ Pulse-Width Modulation (PWM) configurations to govern motor speed and direction. In these configurations, MOSFETs cycle at high frequencies (frequently exceeding 20 kHz to 100 kHz) to avoid acoustic noise and deliver smooth torque output. However, high-frequency switching introduces dynamic switching losses, which can generate significant heat.
WINSOK MOSFETs resolve this issue by balancing low Gate Charge ($Q_g$) with exceptionally low Drain-to-Source On-Resistance ($R_{DS(ON)}$). This reduces conduction losses while keeping thermal generation in check, preventing localized thermal runaway within the robotic actuator.
| Parameters | Performance Range | Target Robotics Applications |
|---|---|---|
| Voltage Range ($V_{DSS}$) | 15V, 20V, 30V, 40V, 60V, 80V, 100V, 120V to 650V | Battery-powered AGVs, high-voltage industrial arms, robotic servo drives. |
| Package Offerings | DFN3X3-8, DFN5X6-8, TO-252, TO-263, SOP-8, SOT-23, TO-220 | Compact logic boards, high-power motor drivers, space-constrained robotic joints. |
| Channel Configurations | N-Channel, P-Channel, N+P Complementary Pairs | H-Bridge motor drivers, power path management, reverse polarity protection. |
Modern robotic designs require compact electrical footprints. Motor drives are frequently integrated directly into joint housings to eliminate long, noise-emitting cable runs. WINSOK’s specialized packages—such as the DFN3X3-8 and DFN5X6-8—provide low package inductance and resistance, delivering high current density in a small PCB footprint. For heavier industrial actuators demanding higher current dissipation, the TO-220 and TO-263 packages offer low junction-to-case thermal resistance ($R_{\theta JC}$), allowing direct heat-sinking.
A high-performance MOSFET requires a robust gate driver and microprocessing unit. Through the deployment of Cmsemicon MCUs, Olukey provides integrated microcontroller and driver combinations that protect against dead-time violations, shoot-through, and over-current events.
By matching the gate driver output impedance to the input capacitance ($C_{iss}$) of WINSOK MOSFETs, engineers can fine-tune switching speeds to minimize electromagnetic interference (EMI) while optimizing total power efficiency.
For global enterprises, sourcing semiconductors requires balancing cost-efficiency with high quality and supply continuity. Olukey Industry leverages the strong electronics manufacturing ecosystems in Shenzhen and the wider Asia-Pacific region to deliver key sourcing advantages:
Ensuring full regulatory alignment and providing localized engineering resources across regional markets.
All WINSOK MOSFETs supplied by Olukey comply with strict environmental and safety regulations, including RoHS, REACH, and CE directives, ensuring smooth entry into European and North American markets.
We enforce strict quality control measures, including AOI (Automated Optical Inspection), X-ray inspection, thermal cycling tests, and high-temperature reverse bias (HTRB) testing to meet demanding robotics standards.
We provide local support teams across key industrial hubs in the Asia-Pacific region, assisting with circuit debugging, thermal simulation, and on-site hardware troubleshooting.
A brief look at our manufacturing footprint and performance envelope.
Robotic applications utilize different parts of our catalog based on their distinct electrical requirements:
Addressing the technical, logistics, and compliance questions of hardware engineering teams.
WINSOK MOSFETs offer comparable electrical parameters ($R_{DS(ON)}$, $Q_g$, thermal resistance) to major global brands, but at a more competitive price point and with more flexible lead times. Our application engineers provide comprehensive cross-reference reports to ensure compatibility with your existing designs.
Complementary MOSFETs combine an N-channel and a P-channel device in a single package (e.g., TO-252-4L). This simplifies layout and reduces component count in H-bridge configurations, which are commonly used for DC motor control in robotic steering and small actuators.
The critical parameters include the Drain-Source Voltage ($V_{DSS}$), which must exceed the motor supply voltage plus safety margins; the Continuous Drain Current ($I_D$), which must handle peak motor stall currents; and the thermal resistance ($R_{\theta JC}$), which determines the required cooling setup.
We provide full schematic reviews, PCB layout optimization for thermal and EMI performance, and prototype development services. Combining WINSOK MOSFETs, Cmsemicon MCUs, and our PCBA development capabilities, we help accelerate your product's time-to-market.
Our products undergo testing to comply with international standards like RoHS and REACH. For automotive and medical applications, we can provide components manufactured in facilities holding IATF 16949 and ISO 13485 certifications.
