ROHM Semiconductor Launches Innovative 1200V IGBTs for Efficiency

ROHM's Latest Technological Advancement in IGBTs

ROHM Semiconductor has recently unveiled its new range of automotive-grade, 1200V IGBTs, aimed at enhancing the performance and efficiency of modern vehicles and industrial systems. These advanced devices not only showcase remarkable low-loss characteristics but also boast a unique high tolerance for short circuits, making them an ideal fit for various applications including vehicle electric compressors and industrial inverters.

Understanding the Need for High-Voltage IGBTs

The automotive and industrial sectors are witnessing a significant transformation, with an increasing demand for devices that can withstand higher voltages. Applications such as electric compressors, high-voltage heaters, and industrial equipment require power components that are not only robust but also energy-efficient. This evolution is part of a broader push toward energy conservation, prompting manufacturers to seek electronics that reduce energy loss and simplify cooling requirements, contributing towards a sustainable, decarbonized future.

Key Features of ROHM's 1200V IGBTs

The newly developed 4th generation IGBTs from ROHM are a direct response to these market needs. By reevaluating both the device structure and packaging, ROHM has successfully created products that deliver industry-low loss characteristics. These IGBTs are engineered for superior short-circuit tolerance, achieving an impressive withstand time of 10µs at a junction temperature of 25°C. They maintain a high breakdown voltage of 1200V while complying with stringent automotive reliability standards.

Advancements in Device Packaging

One of the standout features of these new IGBTs is the innovative TO-247-4L packaging. This design includes four terminals and allows for effective voltage management of up to 1100V in environments deemed 'Pollution Degree 2'. This significant improvement in creepage distance between the terminals means these IGBTs are more suitable for higher voltage applications than earlier models.

Enhancing Energy Efficiency

Efficiency is at the forefront of ROHM's design philosophy. By implementing advanced creepage distance measures, ROHM minimizes design complexities for manufacturers. In tandem, the introduction of a Kelvin emitter terminal in the TO-247-4L design paves the way for high-speed switching, resulting in reduced energy losses. When placed against conventional products in 3-phase inverters, these new packages exhibit around 24% less loss compared to standard solutions and an impressive 35% reduction over older models.

Future Directions for ROHM's IGBT Lineup

As the demand for energy-efficient solutions continues to rise within automotive and industrial sectors, ROHM is dedicated to expanding its portfolio of high-performance IGBTs. This commitment aims to drive innovation in electronics while supporting the broader goals for miniaturization and efficient energy usage in these industries.
