Engineered for high current density, minimized thermal resistance, and optimal performance in demanding Hamburg industrial settings.
The Metropolitan Region of Hamburg stands as a titan of European commerce. From the bustling operations of the Port of Hamburg—Germany’s gateway to the world—to the localized wind energy clusters in Northern Germany, high-performance power distribution systems are undergoing a rapid technological shift. Decarbonizing heavy port logistics, developing clean shore power infrastructures, and building smart grid connections for offshore wind turbines necessitate power electronics that deliver maximum output within minimal volumetric footprints.
Our TOLL (Transistor Outline Leadless) package MOSFETs provide the thermal and electrical performance critical to Northern Germany's engineering ecosystem. Designed as a high-density replacement for traditional D2PAK packages, the TOLL envelope offers a 60% footprint reduction and a 50% height reduction. This spatial optimization directly resolves design constraints in high-current onboard chargers (OBCs), hydrogen electrolysis DC-DC regulators, and heavy duty industrial motor controllers operating in coastal marine environments.
High relative humidity and maritime salinity in Hamburg demand hermetically robust, thermally superior surface mount components. TOLL packages leverage copper-clip interconnects to eliminate internal wire bonds, dramatically lowering parasitic inductance and enhancing resistance to thermal cycling stresses.
Why next-generation power stages specify TOLL and TOLLA form factors over legacy through-hole and SMD housings.
In high-power design, minimizing RDS(on) (static drain-source on-state resistance) is only half the battle. As load currents climb past 200A, the packaging itself becomes the primary bottleneck for both parasitic losses and thermal dissipation. The TOLL-8L package addresses these hurdles via structural redesign:
| Metric | D2PAK | TOLL-8L |
|---|---|---|
| Footprint Area | 150 mm² | 60 mm² (-60%) |
| Profile Height | 4.4 mm | 2.3 mm (-48%) |
| Package Inductance | ~5.0 nH | <1.2 nH |
| Max Lead Current | ~120A - 180A | Up to 340A - 400A |
How Olukey Industry leverages automated semiconductor lines in Asia to secure quality and lead-time predictability for German OEMs.
Navigating global electronics supply chains has become a core competency for modern procurement departments. Our production architecture blends highly automated wafer fabrication facilities with automated optical inspection (AOI) packaging plants in Asia to yield high reliability and scale. By digitizing our supply chain under Industry 4.0 methodologies, we maintain real-time visibility from silicon ingot slicing through package encapsulation to Hamburg port logistics.
We work directly with major original factories as their global general agents, streamlining the distribution layer. This structural arrangement removes third-party broker premiums, allowing us to supply advanced TOLL components at competitive pricing while maintaining the quality assurance standards required by automotive and industrial OEMs in Europe.
HONGKONG Olukey INDUSTRY CO., LIMITED is an integrated electronics component and solution provider. We focus on delivering full-lifecycle hardware solutions centered on three core product pillars: WINSOK MOSFETs, Cmsemicon MCUs, and bespoke PCBA circuit board development.
Serving the global market, we supply advanced high-tech electronic components that help manufacturers optimize their system builds. By integrating our active silicon lines—spanning medium- and low-voltage MOSFETs from 15V to 650V—with advanced microcontrollers, we support application designs in automotive electronics, industrial automation, telecommunications, medical equipment, and renewable energy.
Rather than acting as a simple component seller, Olukey collaborates as an engineering partner. We specialize in cross-referencing legacy, long-lead-time packages to modern TOLL, TOLLA, and DFN formats, helping clients optimize board space and maintain production continuity.
From heavy maritime cranes to grid-connected wind installations, discover where our TOLL MOSFETs drive performance.
Wind projects off the coast of Northern Germany rely on robust grid inverters to condition electrical power. High-voltage TOLLA MOSFETs (such as the 150V WSM180N15) handle step-up conversion and synchronous rectification in power stages, managing heavy current loads with low thermal overhead.
The Port of Hamburg uses electrified reach stackers, AGVs, and container cranes. Low-voltage, high-current TOLL devices like the WSM340N10G handle the quick startup pulses of brushless DC (BLDC) motor controllers, delivering reliable operation under changing load states.
Local microgrids and industrial parks in Hamburg employ Battery Energy Storage Systems (BESS) to smooth out peak demands. In these setups, TOLL MOSFET arrays manage bidirectional charge and discharge states, protecting lithium-ion cells while maintaining conversion efficiency.

Streamlining semiconductor supply lines from China’s automation clusters to Germany’s industrial centers.
For component distributors and OEMs in Hamburg, ensuring delivery predictability is essential. Standard freight lanes between manufacturing centers in Shenzhen/Hong Kong and the Port of Hamburg require optimized transit routing. Olukey coordinates air cargo transport for express sampling, alongside sea-rail intermodal freight networks, to ensure delivery of high-volume production batches within predictable lead-time windows.
We work to prevent supply line interruptions through stock buffering arrangements for our core TOLL/TOLLA MOSFET series. By maintaining safety margins on key part numbers (such as the WSM340N10G and WSM400N06G), we support German assembly houses in managing raw material pipelines, mitigating the impact of spot-market price volatility and fab lead-time extensions.
All delivered batches of WINSOK MOSFETs undergo certification checks to confirm conformance with European RoHS, REACH, and CE environmental directives. Detailed material declarations and quality dossiers are provided upon request to assist clients with compliance validation.
