ROHM announced the new SiC power module “HSDIP20” that combines high efficiency, compactness, and high density for EVs and industrial equipment. By improving design efficiency and reducing mounting area through modularization, we support the progress of an electrified society.
🟦 ROHM Transforms the Future of EV Charging with High-Efficiency SiC Modules “HSDIP20” that Achieve Both Electrical Efficiency and Miniaturization
ROHM’s new HSDIP20 is an ideal power module for PFC circuits and LLC converters used in on-board chargers (OBCs). Features include:
Main features:
- Built-in SiC MOSFETs in 4-in-1 and 6-in-1 configurations in a small package
- Withstand voltage 750V / 1200V, 13 part numbers are available for a wide range of applications
- Up to 52% reduction in mounting area compared to conventional models
- Up to 38°C lower operating temperature at 25W
- Power density: more than 3 times that of top-side heat dissipation discrete
Effects and Benefits:
- Reduction of parasitic inductance and high efficiency by shortening wiring
- Simplified thermal design to reduce the size and cost of cooling system components
- Two overseas companies have already adopted the system, and mass production will begin in April 2025 with a monthly production of 100,000 units.
🟦 Product strategy to meet the need for higher output and smaller EVs
In order to realize a decarbonized society, EV power systems are becoming more and more powerful and voltage. In addition to the demand for higher charging speeds and longer ranges, space constraints for vehicles and equipment are also highlighting the following challenges:
- Heat treatment and layout design close to the limit of discrete configurations
- It is required to support high-voltage and high-frequency operation.
- It is important to improve the efficiency of the implementation and evaluation processes.
HSDIP20 was developed to solve these challenges.
Industry Background and Competitive Trends:
- STMicroelectronics Leads the Market with SiC for Tesla
- Infineon and ON Semiconductor are also rapidly rolling out their products
- ROHM has earned the trust of Lucid Motors, Valeo, etc.
- In anticipation of the SiC market, which is expected to expand by about five times, ROHM plans to invest 510 billion yen
🟦 Summary
ROHM’s HSDIP20 is a power module that brings together the best of SiC technology, and realizes the high efficiency, miniaturization, and high reliability required for EVs and industrial equipment in an integrated manner.
In order to evolve automotive power supplies, “compactness, high efficiency, and heat dissipation” are indispensable.
