Ultra-low RDS(on) technology designed to minimize switching losses in local solar installations and electric vehicle platforms.
The Philippines is witnessing a major transformation in industrial manufacturing, local electronics assembly, and power distribution. With the national commitment to expand renewable energy capacity under the Philippine Energy Plan (PEP) and the rapid adoption of electric three-wheelers (E-Trikes) and electric jeepneys, there is a sharp increase in demand for high-efficiency power semiconductors.
Traditional packages like TO-220 or D2PAK are no longer sufficient to meet modern energy efficiency requirements and space constraints. This is where the TOLL (Transistor Outline Leadless) package becomes essential. The TOLL package offers a 60% footprint reduction compared to a traditional D2PAK, alongside a 50% height reduction. Crucially, the low parasitic inductance of TOLL package MOSFETs minimizes voltage spikes during fast switching cycles, reducing the need for snubber circuits and increasing system reliability.
Saves critical PCB real estate in space-constrained micro-inverters and compact battery management systems (BMS).
Junction-to-case thermal resistance (RthJC) is reduced to less than 0.5 K/W, permitting efficient heat extraction in hot tropical climates.

Bridging Chinese manufacturing scale with high-demand applications in the Philippines.
Off-grid and grid-tied solar systems in islands like Palawan, Mindoro, and Romblon require robust power converters. Our TOLL MOSFETs handle high surge currents and support high power densities in solar inverters and battery energy storage systems (BESS), ensuring long-term thermal reliability under hot, humid local conditions.
As the Philippines shifts to green public transit, E-trikes and E-jeepneys require high-current motor controllers and battery management systems. TOLL packages deliver low-loss current handling (up to 340A for 100V devices), reducing thermal stress on drive systems and extending operating ranges.
Industrial parks in Cavite, Laguna, Batangas, and Cebu house many Electronics Manufacturing Services (EMS). Sourcing Winsok MOSFETs via Olukey Industry offers a cost-effective alternative to Tier-1 brands while matching or exceeding original specifications, allowing EMS plants to remain competitive.
Chinese semiconductor manufacturing has transitioned from simple assembly to high-end packaging. The development of TOLL and TOLLA packages highlights this progress. By using automated wafer probing, wire bonding, and advanced molding compounds, our manufacturing partners deliver consistent quality at competitive price points.
In addition, our close proximity to logistics hubs in Hong Kong and Shenzhen ensures rapid transit times to major Philippine ports. This helps local electronics manufacturers maintain lean inventory setups and minimize supply chain risks.
Essential guidance for design engineers and procurement teams in the Philippines.
TOLL (Transistor Outline Leadless) packages offer a 60% footprint reduction and a 50% height reduction over standard D2PAK formats. The leadless construction significantly lowers parasitic package inductance (typically <1 nH compared to >5 nH in leaded packages). This layout reduces voltage overshoot during high-frequency switching, helps control electromagnetic interference (EMI), and enhances overall system efficiency in power converters.
Winsok's TOLL MOSFETs utilize advanced copper-clip bonding technology inside the package. This design provides an extremely low junction-to-case thermal resistance (RthJC < 0.5 K/W). Under high ambient temperatures, heat is transferred efficiently to the system's thermal management structure (such as IMS boards or heatsinks), preventing thermal runaway and keeping operating junctions within safe parameters.
Yes. Our high-current TOLL MOSFET series (such as the 100V/340A WSM340N10G) are designed for heavy-duty applications, including electric vehicle (EV) motor controllers, battery management systems (BMS), and DC-DC converters. They provide robust avalanche ruggedness (UIS) and low RDS(on), making them ideal for the challenging operating profiles of local utility vehicles.
Yes, we offer direct cross-referencing for various international brands. Winsok MOSFETs cover over 600 models across more than 40 package types, enabling functional and footprint-compatible replacements. This helps engineering teams in the Philippines resolve component shortages, optimize designs, and reduce unit costs.
For standard stocked models, shipping from our Hong Kong or Shenzhen hub typically takes 3 to 5 business days to arrive in Manila, Cavite, Laguna, or Cebu. Custom or large-volume production runs are subject to standard factory lead times, which we confirm during the initial quotation process.
