Select from our vetted inventory of high-performance trench, planar, and dual-channel power semiconductors engineered for advanced power management architectures.
Advanced Driver Assistance Systems (ADAS) have evolved from luxurious safety features to mandatory safety architectures worldwide. Level 2+ and Level 3 autonomous driving functions demand a dramatic increase in high-performance sensors, high-speed computational domain controllers, LiDAR arrays, and high-resolution cameras. With this surge in silicon complexity comes an equally challenging requirement: highly efficient, rugged, and ultra-reliable power management systems.
In this ecosystem, power MOSFETs act as the foundational switches. Whether managing high-current transients in electronic power steering (EPS), safeguarding delicate sensor interfaces from thermal runaway, or powering high-speed LiDAR laser pulses, these components must handle harsh ambient environments and load dump anomalies without failure. For global tier-1 suppliers and EV developers, securing an ODM MOSFET for ADAS supply line with consistent bulk production, zero defects, and high reliability has become a strategic priority.
The shift toward high power density and thermal robustness requires advanced packaging and silicon structures.
Minimizing conduction losses is vital when dealing with high-current autonomous ECUs. WINSOK’s trench technology reduces on-resistance to sub-milliohm levels, mitigating heat generation at the board level.
ADAS sensors are mounted in harsh environments (bumpers, windshields, side mirrors). Our DFN5X6-8L and TO-252 packages offer excellent thermal dissipation (Rthjc) and stand up to rapid temperature cycling.
For high-frequency switching applications like DC-DC converter blocks in ADAS sensor fusion modules, low Qg reduces switching losses and increases system efficiency, directly preserving EV battery range.
| Application Scenario | Recommended Topology | Key MOSFET Requirements | Optimized WINSOK Package | Example Model |
|---|---|---|---|---|
| LiDAR Laser Drivers | N-Channel High Speed Switch | Ultra-low Qg, fast rise/fall times | DFN3X3-8L, SOT-23L | WSD6035DN33 / WST2N7002 |
| Sensor Fusion Domain Controller | Buck-Boost Sync Rectification | Extremely low RDS(on), high ID rating | DFN5X6-8L, TO-220-3L | WSR150N15 / WSR18P10 |
| ADAS Peripheral Cameras | LDO & Power Distribution Switches | Compact form factor, low leakage current | SOP-8L, SOT-23L | WSP4068 / WST2335A |
| ADAS Actuator Protection | Reverse Polarity Protection | High avalanche energy robustness (EAS) | TO-252-2L, TO-263-2L | WSF35P06 / WST8205A |
Global procurement teams face unprecedented challenges: geopolitical shifts, fluctuating wafer yields, and long lead times. For automotive tier-1 manufacturers, an idle assembly line can cost hundreds of thousands of dollars per hour. This risk has driven the transition from just-in-time logistics to supply chain resilience frameworks.
Key requirements for global enterprise sourcing include:
Through OLUKEY INDUSTRY and the WINSOK MOSFET range, global buyers gain access to a dual advantage: direct factory pricing and immediate availability of standard configurations.
How our integrated fabrication and packaging network ensures pricing benefits and consistent quality.
By utilizing advanced automated packaging lines, we achieve highly consistent thermal bonding and lead-frame alignment, significantly minimizing variations in RDS(on) and gate threshold voltage across production batches.
Operating within the Shenzhen and broader Asia-Pacific semiconductor ecosystems, Olukey coordinates wafer fabrication, testing, and packaging locally. This tight integration keeps lead times down to weeks instead of months.
We customize gate layouts, optimize pin configurations, and offer alternative metal plating options to meet specific thermal and geometric constraints of unique tier-1 sensor projects.
Under Hongkong Olukey Industry Co., Limited, we leverage deep regional component expertise to deliver three major product lines: WINSOK MOSFETs, Cmsemicon MCUs, and custom PCBA solutions. This dual capability as a components agent and an integrated developer allows us to understand the application environment on a system level.
By employing statistical process controls (SPC) and real-time optical inspection systems, our manufacturing partner network monitors every phase of the MOSFET assembly. The result is a highly predictable, repeatable, and cost-effective supply of components suitable for both light industrial and demanding automotive applications.
Discover how specific WINSOK MOSFET components function within modern automotive and robotic architectures.
In modern time-of-flight (ToF) LiDAR modules, lasers require high-current pulses within nanosecond ranges to capture environment details. MOSFETs like the WST2N7002 or WSD6035DN33 provide the low input capacitance (Ciss) and rapid gate turn-on speeds needed to drive laser diodes cleanly without trailing pulses, improving overall system accuracy.
ADAS domain controllers synthesize data from radars, ultrasonic sensors, and cameras. They draw varying currents, requiring robust DC-DC buck stages. Medium-voltage N-channel options, such as the WSR150N15 (150V, 150A), handle high power throughput, keeping input lines clean while maintaining minimal thermal output.
Small-form-factor cameras mounted on mirrors or side trims operate under tight thermal constraints. Using DFN3X3-8L packages (like the dual-channel WSD6035DN33) allows engineers to fit two switches in a single compact footprint, saving space and improving thermal dissipation on dense multi-layer PCBs.
In high-power automotive sub-systems, reverse battery protection is critical. P-channel MOSFETs like the WSR18P10 or WSF35P06 are widely selected for active reverse protection circuits, replacing traditional diodes to reduce power loss and improve heat dissipation profile under high load conditions.
