After years of research and development, WISEDRV has achieved a complete closed loop from R&D to mass production in the IGBT module field. As one of the reliable IGBT suppliers in China, the company's independently developed JWH1A400T07S7 series IGBT (400A 650V) adopts trench gate technology and is suitable for various types of scenarios such as industrial frequency conversion, servo drives, welding machines, and uninterruptible power supplies. The products have been used stably for a long time and have established a good reputation in the market.
According to the 2025 data from the Inverter Branch of the China Electrical Equipment Industry Association, the annual demand for IGBT modules in the domestic inverter market has maintained double-digit growth. WISEDRV had already entered this field many years ago and focused its research and development efforts on low switching losses and high operating junction temperatures. They designed an IGBT module with a maximum operating junction temperature of 150°C , which can be combined with copper substrates to enhance heat dissipation. This IGBT module can effectively reduce the system temperature rise and extend the lifespan of the inverter as a whole. Many industrial inverter manufacturers have reported that this module has low switching losses, significantly reducing the on-site failure rate, and has received widespread industry-wide recognition.
In the field of new energy, this module has also passed the verification tests. The WISEDRV IGBT module undergoes full dynamic testing and high-temperature reverse bias screening before leaving the factory. The reverse recovery loss is controlled at a relatively low level, helping customers simplify the heat dissipation design and improve the overall energy efficiency. Thanks to the excellent switching characteristics brought by the trench gate IGBT structure, the product performs stably in scenarios such as motor transmission and servo drives.
From research and development to mass production, WISEDRV has always adhered to its own production lines and rigorous testing and screening. As a supplier of IGBT modules and driver boards for many years, WISEDRV will continue to provide high-reliability products for the fields of new energy electric vehicles, power equipment, medical equipment, and industrial frequency converters, always placing quality at the top of the production standards.
