CORE ADVANTAGES
Engineered for Demanding Automotive Environments

Simplified Thermal Design

Top-cooled packages simplify thermal design by providing a direct thermal path upward for easier mechanical integration

Enhanced System Reliability

Enhance system reliability by reducing heat soak into nearby components, improving overall service life

Lower PCB Cost & Complexity

Reduce PCB costs and complexity by minimizing the need for heavy copper layers and extensive thermal vias

Reduced PCB Temperatures

Keep the PCB temperature cooler by transferring heat into the enclosure or heatsink rather than the board

Higher Power Density

Enable higher power density by supporting smaller designs and closer component spacing

Board Level Reliability

Gullwing shaped leads provide stress relief and prevent solder fatigue and cracking

MARKETS AND APPLICATIONS
General purpose automotive applications
Braking systems DC/DC converters E-boosters ECU management Electric power steering (EPS) Load and power disconnect switches Motor drives / inverters Power distribution units Power and load switching Zonal control units Automotive X-by-Wire Systems Automotive lighting systems

HOW IT WORKS

Directly Cooled by the Heatsink or ECU Case

The exposed top pad provides a low-resistance thermal path, enabling direct heat dissipation to the heatsink rather than through the PCB. With the PCB no longer serving as the primary thermal path, thermal vias can be eliminated — simplifying layout and reducing cost while increasing power density.
