Explore our immediately available product lines designed for high-performance DC-DC power convertors, automotive ECUs, and smart energy systems.
Modern electrical engineering is witnessing an unprecedented paradigm shift. As systems become more consolidated, high-density, and smart, the demand for high-efficiency DC-DC converters has surged globally. Power MOSFETs serve as the heartbeat of these conversion architectures, orchestrating voltage step-down (Buck), step-up (Boost), and buck-boost functions across vast sectors like automotive, computing, telecommunications, and industrial automation.
The post-pandemic supply chain volatilities have fundamentally rewritten sourcing protocols. Standard OEM semiconductor manufacturers have historically experienced volatile lead times, triggering production halts across automotive and industrial sectors. Consequently, tier-1 electronics manufacturers are shifting away from single-source dependencies. Finding reliable, high-performance custom MOSFET alternatives has transitioned from a backup emergency process to a critical strategic directive. Companies now demand "pin-to-pin" compatibility combined with competitive thermal dynamics to secure their supply chain resilience.
HONGKONG Olukey INDUSTRY CO., LIMITED stands at the forefront of this evolution as a premier global solution provider focusing on the overall integration of advanced electronic components. Our comprehensive portfolio centers on three core pillars: high-reliability WINSOK MOSFETs, Cmsemicon MCUs, and bespoke PCBA circuit board solution developments.
By leveraging our deep-seated partnerships and global distribution networks, we support clients in the Asia-Pacific region and worldwide. We deliver high-value semiconductor products to automotive, military, smart industrial, and high-frequency consumer sectors, enabling rapid speed-to-market with exceptional quality control.
"Our corporate mission is to eliminate supply chain vulnerabilities. By developing and distributing top-tier MOSFET alternatives, we ensure that power converter manufacturers maintain uninterrupted production cycles with components that meet or exceed the electrical standards of major legacy manufacturers."
Over the years, Olukey Industry has built a stellar reputation on the foundation of "quality first, service first." We collaborate with global component agents to offer comprehensive support for hardware designers, sourcing managers, and system integrators:
The technological landscape of power management is shifting rapidly. The demand for ultra-compact DC-DC modules with high power density has pushed switching frequencies from tens of kilohertz into the megahertz region. This transition minimizes the size of output filter inductors and capacitors but demands significantly superior performance from the switching MOSFETs.
48V mild hybrid bus architectures, ADAS sensor systems, body control units, and electric vehicle battery management systems require robust, high-reliability MOSFET switches.
PLC power supplies, motor drives, distributed sensor nodes, and smart meters rely on highly efficient synchronous rectifiers to minimize heat footprint in enclosed spaces.
Server power supply units (PSUs) and telecom base stations utilize intermediate bus converters (IBCs) requiring synchronous buck and phase-shifted full-bridge topologies.
To meet these criteria, MOSFET tech roadmaps prioritize minimizing the Figure of Merit (FOM), which is defined as the product of On-State Resistance ($R_{DS(on)}$) and Gate Charge ($Q_g$). A lower FOM translates directly to reduced conduction losses combined with minimal switching loss. WINSOK’s proprietary trench and split-gate technologies offer industry-leading FOM parameters, enabling engineers to design converters that operate at peak efficiency exceeding 95%.
Selecting a component replacement requires a detailed technical assessment to ensure system safety and efficiency. To design a risk-free cross-reference strategy, hardware engineers must analyze several critical parameters:
For high-frequency DC-DC switching applications, dynamic parameters such as Input Capacitance ($C_{iss}$), Output Capacitance ($C_{oss}$), and Reverse Recovery Charge ($Q_{rr}$) must also be carefully matched. If $Q_{rr}$ is too high in a synchronous rectifier topology, it can cause severe voltage spiking, leading to electromagnetic interference (EMI) issues and potential breakdown of the semiconductor die.
To address diverse requirements across different power profiles, the WINSOK MOSFET lineup provides comprehensive package configurations and voltage ranges, making it an excellent replacement for popular models from AOS, ONSEMI, INFINEON, VISHAY, and TOSHIBA.
The product voltages are primarily focused on medium and low-voltage configurations to ensure high-efficiency power switches: 15V, 20V, 30V, 40V, 60V, 80V, 100V, 120V, 150V, 200V, 250V, 300V, 400V, 500V, 600V, and 650V.
Our packaging design supports high thermal dissipation, low parasitical inductance, and compact form factor integration:
WINSOK leverages advanced trench technology and shielded gate structures to optimize charge distribution within the silicon wafer. This technology minimizes conduction losses while lowering gate-to-drain miller charge ($Q_{gd}$).
By transitioning to these modern packages and silicon configurations, engineers can realize substantial savings in component space and BOM costs, while simultaneously achieving a boost in power conversion efficiency.
