The global transition to vehicle electrification requires a complete reconfiguration of the vehicle power management system. Modern Electric Vehicles (EVs) utilize power electronics in almost every subsystem: from high-voltage main traction inverters to auxiliary systems, On-Board Chargers (OBC), DC-DC power converters, and battery management systems (BMS). Achieving high system-level efficiency requires semiconductors that minimize conduction losses, switching losses, and thermal bottlenecks.
As a leading solution provider, HONGKONG Olukey Industry Co., Limited addresses these strict design challenges by providing high-quality, high-reliability components, featuring WINSOK MOSFETs and Cmsemicon MCUs. With a voltage portfolio starting from low voltages up to high voltages (15V to 650V) and available in over 40 distinct package formats, we enable global tier-1 suppliers, automotive factories, and industrial distributors to optimize their power-dense system architectures with precision.
By focusing on modern packaging techniques such as DFN3X3-8, DFN5X6-8, TO-252, TO-263, SOP-8, SOT-23, and TO-220, Winsok components deliver reliable thermal management, helping EV system engineers balance cost and efficiency.
Recent supply chain disruptions have highlighted the risk of relying on a single source. Sourcing managers at EV factories now prioritize dual-sourcing strategies. Olukey Industry offers high-reliability alternatives to Tier-1 power brands, ensuring stable supply chains and reduced lead times.
High-voltage battery platforms require components with smaller footprints. High-density packaging formats like DFN5X6-8 reduce parasitic inductance and lower thermal resistance ($R_{thJC}$), allowing for compact system designs in high-temperature environments.
Automotive components must operate reliably under harsh conditions. Ensuring components meet AEC-Q101 standards helps protect vehicles from early failures, making qualification testing a critical step for EV factory compliance.
We provide comprehensive electronic component solutions, shifting away from standalone component sales to integrated support for entire system designs.
Battery Management Systems require precise cell balancing and load switching. Winsok’s low-RDS(ON) N-channel and P-channel MOSFETs (such as the DFN3X3-8 and DFN5X6-8 series) reduce heat generation in compact enclosures, helping maintain thermal stability and safety in EV battery packs.
Converting high-voltage DC to auxiliary low-voltage rails requires efficient power switches. Winsok’s medium-to-high voltage MOSFETs (60V to 650V in TO-220 and TO-263 packages) help designers optimize switching performance, improve efficiency, and reduce overall unit size.
For windshield wipers, window regulators, and cabin heating controls, our compact SOT-23, SOP-8, and DFN packages offer a reliable solution for high-density vehicle body control designs.
Operating as a global component solution provider, HONGKONG Olukey Industry Co., Limited is based in the Asia-Pacific market and utilizes its global distribution network to supply high-tech electronic components. Over years of development, we have established cooperative relationships with high-tech enterprises and manufacturers worldwide by focusing on quality and reliable service.
Our key advantages include:
Automotive power requirements continue to evolve rapidly. The shift from 400V to 800V battery architectures requires continuous improvement in semiconductor performance. Our product development roadmap focuses on addressing these industry trends:
We are expanding our high-current package offerings, introducing TO-Leadless (TOLL) and LFPAK structures. These packages minimize parasitic inductance and improve thermal dissipation, helping engineers design higher-power systems in smaller spaces.
While silicon-based MOSFETs remain a standard for low and medium-voltage applications, we are developing Silicon Carbide (SiC) and Gallium Nitride (GaN) options to meet the needs of next-generation high-frequency converters and main inverters.
By combining Cmsemicon MCUs with optimized Winsok MOSFET arrays, we provide integrated driver and control solutions that help simplify design processes and reduce component count for system integrators.
