ROHM's Cutting-Edge 1200V IGBTs Revolutionize Efficiency
ROHM Co., Ltd. has made significant strides in power semiconductor technology with its fourth-generation 1200V IGBTs. These components, designed for automotive applications, exhibit remarkable low-loss characteristics while ensuring high tolerance against short-circuits. Such features position them as leading choices for evolving sectors, including electric compressors and high-voltage heaters in vehicles, along with industrial inverters. The initial product offerings encompass four distinct models within the RGA series, available in discrete packages like TO-247-4L and TO-247N, as well as eleven configurations of bare chips, showcasing a commitment to further expansion in the upcoming phases.
Standout Features and Performance
The crux of ROHM's innovation lies in the exceptional short-circuit withstand time, rated at 10 microseconds at a junction temperature of 25 degrees Celsius. Combined with minimal switching and conduction losses, this technology maintains a robust withstand voltage of 1200V, adhering to stringent automotive standards. This innovation is rooted in a meticulous review of the device's architecture and surrounding designs, ensuring high performance and reliability.
Enhanced Package and Voltage Management
A game-changer in the new TO-247-4L package is its ability to handle effective voltages up to 1100V in Pollution Degree 2 environments, thanks to carefully engineered creepage distances between the terminals. This development allows the upcoming devices to adeptly manage higher voltages, catering to a wider scope of industrial applications.
Reducing Design Complexity for Manufacturers
By integrating creepage distance measures directly into the device, ROHM alleviates the design challenges often faced by manufacturers. The high-speed switching capability of the TO-247-4L package is further enhanced by a Kelvin emitter terminal, contributing to a notable reduction in losses. Comparative analyses demonstrate that using ROHM's innovative packaging results in approximately 24% less loss than standard products, and a 35% reduction compared to earlier models, thereby promoting improved efficiency in drive applications.
Growth and Future Developments
ROHM is poised to broaden the scope of its high-performance IGBT lineup, propelling advancements in miniaturization and enhancing drive efficiency across the automotive and industrial equipment sectors. These new technologies not only signify a leap forward in semiconductor design but also reflect ROHM's unwavering commitment to meeting the evolving needs of the market.
