Onsemi FFSH5065A: A 650V, 60A Field Stop II Trench IGBT for High-Efficiency Power Conversion

In the realm of power electronics, the demand for higher efficiency, greater power density, and improved reliability continues to drive innovation in semiconductor technology. Addressing these needs, onsemi introduces the FFSH5065A, a robust 650V, 60A IGBT that leverages advanced Field Stop II Trench technology. This device is engineered to deliver superior performance in a wide array of high-power switching applications, from motor drives and inverters to industrial SMPS and renewable energy systems.

The core of the FFSH5065A's performance lies in its state-of-the-art architecture. The Field Stop II (FS II) technology significantly enhances the device's capabilities compared to previous generations. It enables a remarkably low Vce(sat) (collector-emitter saturation voltage), typically around 1.55V at 30A and 25°C. This low saturation voltage translates directly into reduced conduction losses, a critical factor for improving overall system efficiency, especially in high-current applications.

Furthermore, the trench gate structure ensures excellent charge control, which contributes to low switching losses. The combination of low conduction and switching losses allows system designers to push for higher switching frequencies without incurring a severe efficiency penalty. This capability is essential for reducing the size and cost of magnetic components (inductors and transformers) and filters, thereby increasing the overall power density of the end product.

The device is also characterized by its tight parameter distribution and positive temperature coefficient, which simplifies the critical process of paralleling multiple IGBTs for even higher current requirements. This feature ensures current sharing stability across parallel devices, enhancing reliability in large-scale power modules.

A key strength of the FFSH5065A is its robustness and reliability. It features a short-circuit withstand time of 5µs, providing a crucial safety margin in fault conditions. The co-packaged ultra-fast soft recovery diode offers optimized reverse recovery characteristics, minimizing switching noise and voltage overshoot, which further protects the IGBT and increases the longevity of the entire system.

From an application perspective, this IGBT is an ideal choice for:

Motor Drives and Control: Providing efficient and reliable switching for industrial AC drives.

Uninterruptible Power Supplies (UPS): Ensuring high efficiency in power conversion stages.

Solar Inverters and Renewable Energy Systems: Where high efficiency and durability are paramount.
