Explore our highly integrated N-channel, P-channel, and Dual MOSFETs optimized for high-temperature and high-density automotive Electronic Control Units.
"Security of supply is no longer just a purchasing metric—it is a critical engineering design variable. Introducing qualified pin-to-pin functional equivalents has become an industry standard for Tier-1 automotive developers."
Adhering to zero-defect principles, our automotive alternatives undergo stringent electrical parameter validation, static/dynamic parameter screening, and package inspection to guarantee performance under high thermal stress.
WINSOK MOSFET's voltages cover 15V to 650V in advanced packages like DFN3X3-8, DFN5X6-8, TO-252, TO-263, SOP-8, SOT-23, and TO-220, matching the diverse form factors of existing ECU hardware configurations.
We provide localized engineering support, failure analysis (FA), and application-specific modifications. Our teams assist Tier-1 developers in selecting the correct gate drive parameters and thermal models.
Analyzing key structural trends driving the adoption of alternative power semiconductor channels in modern vehicle manufacturing.


Modern packaging, such as the DFN5X6-8 and TO-263, allows for top-side and bottom-side cooling. Olukey Industry supports engineering teams with detailed thermal simulation profiles to ensure the structural longevity of alternative MOSFETs under continuous operating loads in high ambient environments.
Leveraging Cmsemicon's high-reliability microcontrollers, we deliver reference designs where the MCU's PWM outputs are optimized for WINSOK MOSFET gate capacitances. This minimizes switching latency and mitigates voltage overshoot, providing an integrated subsystem solution.
