Our top-tier leadless power packages deliver exceptional thermal dynamics and continuous high-current metrics designed to withstand standard industrial operations throughout Hungarian automotive corridors.
The industrial landscape is undergoing a critical migration from legacy through-hole and classic SMD components (like D2PAK or TO-220) to next-generation leadless formats. Foremost among these is the TOLL (Transistor Outline Leadless) and TOLLA packages. Engineered for ultra-high current capability, thermal efficiency, and footprint consolidation, TOLL package MOSFETs mitigate key engineering constraints: space limitation, parasitics, and thermal bottlenecks.
Our team at HONGKONG Olukey INDUSTRY CO., LIMITED works closely with tier-one suppliers and designers across Europe, primarily serving Hungary's growing industrial sector, to deploy these chips directly into next-gen assemblies. By offering low internal resistances (RDS(on) down to sub-milliohm levels) and utilizing high thermal dissipation efficiency, these components help engineering teams build lighter, cooler, and highly dense power modules.
Over the past decade, Hungary has emerged as one of the preeminent manufacturing and assembly hubs for the Central and Eastern European (CEE) automotive industry. With global manufacturers establishing major facilities in cities like Győr, Debrecen, Kecskemét, and Esztergom, the local demand for rugged, high-reliability semiconductors has escalated. Furthermore, the massive influx of electric vehicle (EV) battery Gigafactories across the country has intensified the requirement for robust Battery Management Systems (BMS), DC-DC converters, and thermal management units.
In this local ecosystem, reliability isn't just a metric; it's a structural requirement. Hungarian tier-1 automotive suppliers require parts that comply with strict AEC-Q101 standards and demonstrate long life expectancy in harsh environments. TOLL MOSFETs, with their low thermal impedance (RthJC) and superior mechanical robustness under temperature cycling, are replacing D2PAK components in these localized automotive assemblies.
The core advantage of the TOLL package over legacy packages like the D2PAK (TO-263) lies in its physical form factor and connection technology. TOLL offers a 30% smaller footprint and a 50% height reduction, allowing systems to shrink overall volume. However, the true performance gain is measured in electrical parameters:
Internal package lead wires in traditional MOSFETs are replaced by copper clip-bonding or layout leads in TOLL packages, reducing package inductance from ~5 nH down to less than 1 nH. This directly curbs voltage overshoot during high-speed switching.
The large exposed drain pad in TOLL packages is soldered directly onto the PCB, achieving an exceptionally low junction-to-case thermal resistance (RthJC). This design handles currents up to 340A without overheating.
By using a dedicated Kelvin source connection pin, TOLL packages isolate the gate-drive return loop from the main high-current source path, protecting gate signals from transient voltage spikes.
Our TOLL series MOSFETs, including the WSM340N10G and WSM320N04G, are actively engineered to support multiple high-demand industrial scenarios across Hungary:

As switching frequencies and voltage requirements rise, power electronics are evolving toward hybrid structures. The current technology roadmap targets lower internal resistance and better gate charge configurations (Qg × RDS(on) figure of merit). In the medium-voltage range (40V to 150V), TOLL remains an efficient silicon (Si) option, delivering high current handling without the cost of wide-bandgap alternatives.
Our research and development partners are actively testing advanced silicon-on-insulator (SOI) and multi-trench technologies to improve performance. For Hungarian and global system designers, this ensures a path toward higher performance, drop-in compatibility, and long-term security of supply.
Everything you need to know about TOLL MOSFET integration, thermal performance, and Hungarian supply chains.
TOLL packages offer a 30% reduction in PCB area and a 50% reduction in profile height compared to D2PAK. More importantly, they decrease parasitic package inductance from ~5nH down to <1nH. This reduction in parasitics helps manage high-frequency voltage spikes, allowing designers to minimize the size of snubber circuits in electric vehicle traction inverters and onboard chargers.
Yes. OLUKEY distributes Winsok automotive-grade MOSFET series that undergo specialized manufacturing screenings to meet AEC-Q101 specifications. We provide complete validation documentation, PPAP packages, and reliability test reports for automotive applications in Hungary and other European countries.
For standard in-stock inventory, delivery to major industrial hubs like Győr, Budapest, and Debrecen typically takes 5 to 7 business days. For customized OEM production runs or large bulk orders, delivery timelines depend on current wafer availability and are confirmed at the time of inquiry.
The Kelvin Source pin isolates the gate loop return line from the high-current source connection. This prevents the high dI/dt transients in the power source path from injecting noise into the gate circuit, helping prevent false triggering and maintaining signal integrity in high-current applications.
